Template:Infobox South Park episode
"Erection Day" is the seventh episode of Season Nine, and the 132nd overall episode of South Park. It aired on April 20, 2005.
Jimmy starts unintentionally 'pitching a tent'. The boys consider entering the talent show to try to win the prize of a $100 South Park Mall gift certificate.
In this episode, Jimmy Valmer faces a dilemma because he begins to experience spontaneous premature erections (although they only occur when Jimmy is the focus of attention). Even after looking forward to it for some time, this makes him afraid to enter the South Park Elementary Talent Show for fear that he would be embarrassed in front of the entire school. He consults Butters Stotch, the only kid in town whom he thinks would be unlikely to make fun of him. Butters explains to him that if a man's penis is erect, he needs to put it into a woman's vagina and it will 'sneeze some milk'. After this, he says, the penis will weaken again. Jimmy concludes that if he doesn't want to get an erection during his performance, he should have intercourse before he goes up. He attempts to arrange a date with a girl named Shauna from school, with Cartman's help. Jimmy ruins his date when he says, "I am so glad you think so Shauna, because I really want to stick my penis into your vagina." When this ultimately fails, he goes to the red-light district of town called Colfax Point (based on a suggestion from Officer Barbrady), trying to get laid, while at the same time the Talent Show starts back at school.
While a string of bad performances occur at the school (including Butters forgetting the words to his apple song and subsequently wetting himself, Cartman doing a dead-on impersonation of Tony Montana from the 1983 film remake of "Scarface", and the Goth Kids performing "Talent Shows are for Fags"). Jimmy picks up an obese prostitute going by the name 'Nut Gobbler'. The naive Jimmy attempts to woo her by taking her to a restaurant but her pimp 'Q-Money' comes in and, thinking she is betraying him, grabs her and goes off to kill her. Jimmy follows suit in a bizarre car chase. In the end, Jimmy manages to subdue the pimp with his comedy routine, while Nut Gobbler clubs him on the back of the head. Jimmy then picks Nut Gobbler up and carries her, getting applause from prostitutes, into a building on which the sign reads 'Ho-Tel'. Then, when the talent show is about to end, Jimmy hurries onstage at the Talent Show at the last moment. He begins his routine, but then he suddenly gets another erection. The episode ends with him exclaiming, "You gotta be kidding me". The credits begin before the viewer is able to discern the consequences of what happened.
