You Got F*cked in the Ass - S8-E4
Audio problem: After Stan does the line dance while the other team announces that "its on", and the bystanders are watching. As the blonde haired white guy says "Oh Lord its on." The Asian kid from the group is saying the exact same thing. However you don't hear his voice.

Revealing mistake: When the "Asian Kid" is first introduced on the Dance Dance Revolution machine, the arrows are going up the left side (Player 1 side) of the screen, but he is obviously playing on player 2's side. To make matters even worse, the dance pattern on screen doesn't match the way he's dancing, yet the screen also shows that he's doing pretty well.

Continuity mistake: The end of the show where the dance battle takes place, when Butters is tap dancing his left shoe comes off but when it goes back to him his right shoe is off.
Answer: He appears in at least 5 other episodes, but usually just as a background character. He can be seen at Cartman's party in "Immaginationland". He was also one of the kids trying out to replace Butters in the "Professor Chaos" episode.
