After Kid Buu is killed, Goku, Vegeta, Hercule, Dende, and Good Buu all return to Earth. Six months later Goku and the others wish for the Earthling's memory of Majin Buu to be erased and he's free to go get into all sorts of shenanigans out in the city. He wins a fight and gets money for ice cream and then helps Bulma carry her grocery bags home. Majin Buu and Bulma thwart a jewelry store heist who are really the guys he "accidentally" beat up the first time. Saiyaman and Saiyagirl, his new sidekick/girlfriend, arrive just in time (too late). Later, Goku, Trunks, and Goten are in the hot tub and the boys fuse and attack Super Saiyan Goku in a playful fight. The tub breaks and the two are left standing in front of their friends naked and Goku laughs while Chichi runs after Gotenks to spank him just like in the good old days.

Because the independent FUNimation dub began at episode 54, it was not until several years later that FUNimation acquired the rights to seasons 1 and 2 from their former distributor Geneon. After receiving the rights to the first two seasons, FUNimation redubbed the original shortened 53 episodes with their own voice actors for TV Broadcast. They planned to release these uncut episodes in the Ultimate Uncut series of DVDs with the first volume available in April of 2005. However, this DVD set was never completed, and the 67 uncut episodes (along with the other 224 episodes of the series) were instead later released in the FUNimation Remastered Box Sets . However, all 67 uncut episodes were also aired on Cartoon Network in the summer of 2005 beginning in June, two years after the finale of the series on Toonami.
