Hey, my name is Jeffy, see? It says it on my shirt, Je-ffy. You wanna see my pencil, you wanna see it?
— Jeffy's Introduction
Jeffy Jeffy Mario (né Francois) or simply Jeffy is a character in SuperMarioLogan . He is voiced by Lance Thirtyacre and Anthony Miller who does the animal noises. Jeffy has a tendency to put pencils in his nose and spank his diaper often. He is the adopted son of Mario and his enthusiastic girlfriend Rosalina, whom he calls "Mommy". He is also known for his fairly new catchphrase "ARE YOU FUCKING HIGH?!", as well as his recent habit of cussing people out.
Because his father is the late painter Jacques Pierre Francois, Jeffy is of French descent and extremely skilled at painting. His mother Nancy Jeffy turned out to be an abusive mother and prostitute. Mario adopts Jeffy after his abusive mother is arrested for child abuse, prostitution, and a number of other things. Mario does this in hope that when Jeffy turns 18 he gives Mario some of his bond money.
Jeffy is very tall and lanky with short posture. He wears a blue bicycle helmet, has a pencil shoved up his nose, along with an orange-yellow t-shirt that says "jeffy" on it. He wears short dark blue jeans with a diaper outside of it, which he occasionally spanks, and wears black sneakers (which have been said to be branded by Adidas). His biological appearance seems to be his blue eyes from his mother, and his black hair from his father. He is caucasian, his face is oval shaped with two teeth, and a round nose, along with two eyelashes and a unibrow.
Life outside the USA
Jeffy was born in a porta potty in Paris, France in 2004. He never attended any school due to his mother lacking any sort of care for him. After his parents possibly got divorced, Jeffy was taken by his mother and smuggled into Pensacola, Florida as an illegal immigrant. Jeffy was then dropped off at Mario and Bowser's apartment because his mother was tired of his stupidity. He now lives with Mario and his family in the New House
Jeffy has displayed acts that can be seen as outright idiotic. He has a bad habit of spanking his diaper despite some fans which strangely happens to be outside his pants. When he is called a "bad boy," he tends to throw have a meltdown by throwing his head onto any surface, but calms down when he is called a "good boy." He likes to put his "pee-pee" in stuff, especially Cheerios cereal boxes. Jeffy has a tendency to throw epic meltdowns when he does not get his way, no matter how small the situation is. He is also afraid of the most retarded things such as hippos, toilets, animal cards, snow, scary ostriches, the flu shot. His parents delivered him to Mario because his mom did not want to look after him (according to Jeffy). Not much is known about his relationship between Bowser Junior and Joseph despite the fact that both called him awesome after surviving a game of Russian Roulette once. Rosalina is more loving and caring towards Jeffy, to the point of acting like a motherly figure and calling Mario off whenever he spanked Jeffy.
Jeffy, however, has been shown to act smart, but in a dumb way at times, such as in Jeffy's Homework! when he reasoned that 8-4=8, since they are taking 4 out of the equation, even going on a profanity-laced rant. Later, in Jeffy's Bedtime!, he called the nameless tall character in Green Eggs and Ham a liar since the character claimed that he liked the green eggs and ham, but the illustration clearly shows that he didn't eat the ham at all. According to him, he used to live at 7 Jeffy before being dropped off at Mario's door. Jeffy also tends to soil his pants a lot. Jeffy has been proved to be intelligent, despite his rather or example, in "First Day Of School!", he was smart enough to tell the teacher off for assigning a 10-page paper that was due the next day (though he got a note sent home for doing so). Sometimes even more so than Junior, as seen in Jeffy's Bedtime!, where he demands that Mario and Rosalina make his green eggs and ham, in "Jeffy Gets Potty Trained!", when he demands that Rosalina give him marshmallows instead of peas, in "The Hitman!", where he wanted Jello after Mario gave him green beans, and he refused to eat his nuggets because he wasn't given 20 toys and threw them away, and finally in "Locked Out", where he demanded for chocolate cake, cried when Mario didn't give him chocolate cake and locked Mario out just so he could teabag Mario's plate of cake. He also flips his desk in "First Day Of School!" because the teacher assigned a 10-page essay that was due the next day and cusses (mostly the F-word) at Jackie Chu.
Jeffy sometimes seems have a prankster personality as in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Junior. During both of these videos, he seems to be less unintelligent, causing many fans to think that this could be a normal version of Jeffy, despite all of his intelligent moments in the series.
When his real mother Nancy tried to claim him back, Jeffy begged Mario to let him stay and promised to be a good boy (and kept his promise by not playing the cat piano when he went back inside), indicating that he loves Mario very much.
Jeffy is also a bit of a pottymouth. He possibly got this from his mother who swore at him a lot.
Sick Jeffy is a form of Jeffy with the flu, taking way greater effect than normal Jeffy would with other characters such as Mario, and having a chance of giving others the flu. His appearance also changes to rundown, tired, and overall extremely droopy.
Smart Jeffy is a form of Jeffy, appearing only in the episode of the same name, who is incredibly smart compared to his normal form, due to his pencil having impaled his brain because of a freak accident indirectly caused by Junior. However, at the end of the video, Jeffy sneezed, blowing his pencil out back down his nose, leaving a hole in his brain, and reverting him to his normal form.
Emo Jeffy is a more depressed version of Jeffy with emo clothing and hair.
Green Bean Jeffy
Due to the Green Bean Giant being angry at Jeffy for not eating green beans, he cursed Jeffy to turn him into a human-size green bean. The curse eventually wore off after Jeffy ate a whole plate of green beans, reverting him to his normal state.
Mario is Jeffy's adoptive father. Mario has an apparent strong dislike of Jeffy, but deep down, he loves him. This is pretty much confirmed in Jeffy's Parents! However, Jeffy likes Mario. Jeffy usually calls Mario "Daddy". Mario finally adopted Jeffy after a year in Jeffy's Parents!
Mario was incredibly unhappy that Jeffy was dropped off at his apartment door and loathes the fact he has custody of Jeffy. Mario gets frustrated with Jeffy in nearly every video they appear in together. Most of the time, however, it seems that Jeffy annoys Mario, not on purpose. Mario has tried multiple times to get rid of Jeffy, but to avail. Most of his attempts ended with Jeffy back at Mario's step or in the case of Where's Jeffy?, Mario going back to get Jeffy because he had Rosalina's necklace, only to find out that Jeffy gave it to a squirrel. In Bowser Junior's Nerf War!, both Mario and Jeffy even made a small cameo appearance right at the end and Mario attacked Jeffy with a Nerf gun. Jeffy gets Mario into trouble often, which Jeffy finds humorous.
Although Mario gets annoyed with Jeffy most of the time, he has been shown to care about Jeffy, as shown in Jeffy's Mistake! when Black Yoshi was about to kill Jeffy; in Rosalina's Parents!, Mario gets scared when he assumes Jeffy fell to his death and freaks out when Jeffy gets abducted. It's possible Mario might only care just so Rosalina won't break up with him. Despite all this, they deep down love each other and cant live without one another;
Chef Pee Pee
Jeffy seems to like Chef Pee Pee. Chef Pee Pee, however, does not seem to have patience for Jeffy, almost as much as Mario; for instance, he got annoyed with Jeffy when Mario and he were trying to get Jeffy to eat his green beans. Chef Pee Pee also seemed upset when Jeffy ruined the pencil cake Chef Pee Pee made for him in Jeffy's Birthday!.
Jeffy and Rosalina seem to get along well, especially on Rosalina's side. She copies Jeffy a lot. Jeffy usually calls Rosalina "Mommy" just like how he calls Mario "Daddy". Rosalina acts like a deep motherly figure to Jeffy, to the point of sometimes caring more about Jeffy, and calling Mario out whenever he abuses Jeffy, even breaking up with Mario when he heartlessly let Jeffy go with Nancy.
Jeffy and Bowser Junior are very good friends. They enjoy hanging out with each other and make a good team. When both Jeffy and Junior met for the first time in [[Bowser Junior's Game Night 3], Junior called Jeffy awesome for surviving a game of Russian Roulette. Jeffy was indirectly also the reason for Mario and Junior permanently recognizing each other starting from that episode, and he also seems like Junior. As of recently, both Junior and Jeffy seem to get along more, as shown in Shrek The Babysitter!Smart Jeffy. Junior even caused the main plot elements of Smart Jeffy and Jeffy Loses His Teeth!, wherein he made Jeffy jump from a trampoline and hit a table in the former, and accidentally knocked one of Jeffy's teeth out with a T-ball bat in the latter.
Jeffy's Mom (Nancy)
Jeffy's mom, whose name is Nancy, debuted in Jeffy's Parents!, and she was shown to be very abusive towards him, to a much higher extent than Mario was. Nancy acted like she cared about him when people were around, but when they were alone she would always beat him. Nancy eventually got arrested and Jeffy ended up getting adopted by Mario.
Jeffy's Dad (Jacques Pierre François)
Not much is known about Jeffy's relationship with his dad, world-renowned French painter Jacques Pierre François, who had died after committing suicide in pursuit of his art. Due to the fact that Jeffy's "IF LOST" paper contains Jacques's name and address information, this could imply that Jacques used to care about Jeffy.
In Jeffy's Sister!, it was revealed that Jeffy has a sister named Feebee. Jeffy and Feebee are very similar in character, with nearly the exact same traits. They can even communicate to each other through diaper patting, somehow. However, because she has, so far, only appeared in Jeffy's dream, some speculate that because she was not dropped off along with Jeffy, Feebee either possibly never had been dropped off, never existed in the first place, or may probably be even dead.
Jeffy seems to be the most controversial SML character ever created and has been panned a lot by many SML fans, including Dabhdude and GamecubeDude300. People truly criticize the fact that he tortures Mario in some videos. People have even suggested that Jeffy should go back with his real parents in the video "Jeffy's Parents!", getting rid of him permanently (a few have gone even far as to suggest killing him off).
Despite the character's negative reception received so far, other fans have argued that Jeffy's negative reception is mostly due to Jeffy's Bad Word!, in particular, which has gone on to become of the most infamous and controversial SML Movies to date, because of Jeffy saying faggot and annoying Mario for half the video.. They essentially argue that ever since the release of this controversial episode, they automatically reject any episode that has Jeffy in it at all; for example, many fans point out that Jeffy haters complained about Rosalina's Parents! for having Jeffy in it, despite the fact that Jeffy only had about one minute of screen time and was not even the main focus of the episode. Locked Out also fueled Jeffy's negative reception, becoming the most disliked SML video of all time, beating Jeffy's Bad Word! with over 4,000 dislikes. This makes them the two most disliked Jeffy videos.
Just to note, not everyone hates Jeffy, and this has been pointed out by Logan. While most people dislike Jeffy to some extent, a few people, particularly in the YouTube comments enjoy his appearances. Some people can also like him if he is being a "good boy."
After Jeffy's Parents!, fans reconsidered their opinions on Jeffy because his mother made him the way he is, finally recovering his former mixed to positive reactions, with the exception of some fans, such as GameCubeDude300.
Unfortunately, Jeffy's reception declined once again after his appearance in Jeffy's Tantrum!, when he starts acting like an idiot to Mario and tried to kill himself because he wouldn't get the Spongebob game on his iPad. However, others were glad that Mario refused to cave into Jeffy's demands, unlike in the past.
Luckily, after Bowser Junior's Playtime 5, his positive reception has increased, due to Jeffy acting somewhat funny during the playtime scenes.
However, despite what is stated above, there are still many more Jeffy haters than fans, due to Jeffy continuing to torture Mario, contradicting his promise to become a good boy in Jeffy's Parents!. In spite of this statement, younger fans seem to be fond of Jeffy, and in many cases, dislike a video if Jeffy does not have an appearance in the video.
Many fans complained by saying that Jeffy is offensive and that he makes a mockery out of those with low-functioning autism. Later, Logan stated that Jeffy is supposed to be funny like Chef Poo Poo, not mentally disabled. Others don't like Jeffy because he only exists to make Mario miserable. This is a mistake that Brooklyn T. Guy has made in Jeffy's Stupid Home Video!.
Logan has insisted that Jeffy is not mentally retarded, just extremely unintelligent.
It has not been confirmed if Jeffy is mentally disabled and retarded.
Sometimes when Jeffy is really upset, he says, "ARE YOU FUCKING HIGH?!"
Jeffy's original address is 7 Jeffy Street, Paris, France.
He has been constantly abused by Nancy, his mother. (which in turn may be the reason for him treating Mario badly)
Jeffy is 12 years old, and he is of French descendant.
It is likely that Jeffy's actual name is Jeffy François.
In the Pokémon series, Jeffy owns a Cookie Monster and somehow taught it Thunderbolt.
Despite being slightly unintelligent, Jeffy is still able to do many impressive acts, such as accurately painting the Mona Lisa on his Easter egg, finding a golden egg even though Mario threw it away, saying the full alphabet backward, and getting random articles of clothing out of thin air.
Jeffy sometimes speaks normally, and sometimes in 3rd person.
Jeffy is so far the only character to strike the same identical pose in the videos' custom thumbnails. So far, he has used two, one that lasted from his debut up to Jeffy's Mistake!, and another that lasted from the aforementioned video onwards.
His theme song is Doh De Oh by Kevin MacLeod.
Jeffy has his own unofficial Facebook page and an Instagram page.
In Jeffy's Birthday!, it is revealed that Jeffy's birthday is on August 21, and his birth year (2004) was revealed in Jeffy's Parents! after the other half of his "IF LOST" paper was recovered.
The Jeffy puppet can be found on the Etsy website. The Jeffy puppet on Etsy costs $500.
According to some fans, he is similar to Billy from "The Grim Adventures of Billy and Mandy" as both like to put stuff in their noses.
