The video starts out with Junior proving Joseph that the earth is flat. Joseph denies saying that the earth is round. Junior said that since a map is flat, earth is too. Joseph said that since the globe is round, earth is too. They argue for a bunch and then decided to ask Cody. Joseph grabs his phone and Cody said he has no time since his sister is visiting.

They see Katy who is Cody's sister that wears all pink rather than blue. Junior and Joseph fell in love with Katy. Cody told Junior and Joseph that Katy is his twin and they denied. Junior continues to argue with Cody. Junior then ask Katy if the Earth is round or flat and Katy said round. Junior disagree and gives a reasoning that a basketballs are round but basketball courts are flat and Joseph then agrees with Junior. Cody got mad and went banging his head near the wall on the other side. Junior and Joseph then argue who to get Katy and they decides to ask Cody. We then see Cody banging on the wall. Junior and Joseph ask Cody and Cody said no one can date his sister Katy. They then went ask Katy what to do and Katy said weird stuff on the Effiel Tower. Junior then decides to play Spin the Bottle. Junior explain the rules to Katy. Cody denies but Junior told him if the bottle lands on Cody and Joseph, they have to kiss and Cody agree.
