Rosalina is talking with Mario when Jeffy enters the room and tells Mario that he gave his shirt to a pig. Mario asks why Jeffy would do that, and Jeffy responds with fucking around in order to be late. Mario then sees the pig rolling in mud. Mario takes off the shirt and washes it. The shirt is blank and Jeffy doesn't know his name. Once Jeffy goes to school, he tells Junior that he doesn't know his name, so Junior writes "Poopy Butt" on Jeffy's shirt. Junior then tells Jackie Chu that "Poopy Butt" is a new student. Jeffy introduces himself as "Poopy Butt." Jeffy starts walking home when he needs to tie his shoe. King Strongbottom is seen driving when he hits Jeffy with his car by accident. Strongbottom offers Jeffy $1,000,000 if he doesn't tell anyone what happened. Jeffy then tells Mario that Strongbottom gave Jeffy $1,000,000. Mario and Jeffy celebrate, but Mario then realizes that the paycheck is signed to Poopy Butt. Chef Pee Pee is seen calling his father when Mario tells him that Jeffy got paid $1,000,000, but Jeffy signed the check as Poopy Butt. Mario then calls Goodman. Goodman states that he changed his name to Poopy Butt and cashed in the check. Mario walks away crying. Chef Pee Pee then reveals that he also changed his name to Poopy Butt, and he asks Mario where the paycheck is. The video ends with the question, but Chef "Poopy Butt" is still asking Mario where the check is.

- When Jeffy informed Rosalina that school started in five minutes, he showed only four fingers to emphasize this fact, as the Jeffy puppet has only four fingers on each of its hands.
- Mario said the bank wouldn't accept a "shirt" with Poopy Butt written on it, instead of check.
- When Goodman says Mario and Jeffy "wasn't" named Poopy Butt, he should've said weren't or aren't.
- King Strongbottom called Chef Pee through a phone. However, in his past appearances, he had no idea what a phone was. It was possible Chef Pee Pee or someone else taught him.

- Jeffy, Mario, Goodman and Chef Pee Pee mention King Strongbottom's Escalade as a "truck". This is not true as Cadillac Escalade is actually an SUV Car.
