Something You Can Do with Your Finger

 is the ninth episode of the fourth season of South Park. It first aired on July 12, 2000.

Plot
After having a dream in which he, Stan, Kyle, and Kenny are part of a successful boy band, Cartman decides to make this dream a reality; in hopes of gaining US$10,000,000 from it. He gets Stan, Kyle, and Kenny together and they have other kids try out as a fifth member. Butters auditions; singing Little Bunny Fu Fu, Ike auditions; sings various songs that don't impress Cartman; Wendy is the best one they could find, and she agrees to dress like a boy. Cartman calls their group “Fingerbang”, after a phrase he believes to mean when you use your hand and pretend it’s a gun (though Kenny reveals the true meaning of the word to them, which Cartman cites as sick: "Who the hell would do that?! Grow up, will you Kenny?"). They then attempt to get a gig at the mall, but two security guards mistake them for juvenile delinquents, and give them trouble for it. So Cartman has to sneak into the announcement office and says free orange smoothies starting a riot causing the mall cops to try to stop it.

When he hears about the boy band Stan is now a member of, Randy freaks out and inexplicably orders him to quit it. Later, he explains that back in the 1980s, he joined a boy band, and consequently dumped his friends and family, and dropped out of school. The band was successful for a few years, and made millions of dollars, until the owner decided that the members were getting too old to be in a boy band, and had them replaced. He then suffered heavy debt, and was forced to sell everything he owned in order to return home, and had to use what little money he had left resuming his education.

After a while, he decides that Stan can only learn by making his own mistakes, and allows Stan to play in the band. The gig is late, and under threat of being canceled, so they rush over to the mall. Though they make it there in time, Kenny gets crushed to death by an elevator, and the band seems doomed without five members. Then Randy steps in and replaces Kenny. After performing the song, for whatever reason, they decide the “fame” they receive is too much, and the band goes on a hiatus. Or rather, retires altogether. Then Randy offers to get them all orange smoothies but Stan replies "I don't think they sell them anymore".
