In the episode, the fourth grade girls have made a secret list that rates every boy's looks from cutest to ugliest.
The boys, after two attempts, eventually succeed in stealing the list and discover it ranks Clyde as the cutest, and Kyle as the ugliest, with Cartman just above him.
Kyle's spirits plummet after this discovery, while Clyde's ego inflates dramatically and he starts flirting with many girls at school.
Kyle, in an act of depression, starts hanging out with the ugly kids, and gets the idea from a boy named Jamal to burn the school down.
Kyle decides to go ahead with his plans of arson regardless, citing the long wait he would have to endure in order to realize this blessing, and the hardships and misery he would suffer in the interim.
Unfortunately for Wendy, Stan has not quite lost his habit of throwing up out of nervousness and her attempt to kiss him is interrupted when he vomits in her face, but this marks their reconciliation and they resume their romantic relationship.
