In the episode, Stan has been challenged to a dance-off, and it is up to him to put together a team of South Park's best dancers to compete against a troupe from Orange County, California.
Stan and his friends are playing with radio-controlled cars when a group of kids from Orange County come and dance in front of them, thus "serving" them.
Chef immediately shows great concern and calls their parents to inform them about the ordeal and assure them that their children are safe.
It is revealed through flashback that, in 2002, Butters' shoe flew off during the national Tap-Dancing Finals, hit a stage light in the rafters, and led to an extremely gruesome chain of events that left eight people in the audience dead.
Butters flatly refuses to participate in the show, even after further pressing, so the team has to settle for a dancing duck named Jeffy from a local farm.
However, during the performance, Butters' shoe flies off again and hits a stage light, causing the rafter to fall on and kill the entire Orange County team and their coach.
