Cory wins a girl's heart with a little politeness – but he better stay respectful, because she's Harley Keiner's kid sister, Theresa, also known as "T.K.", who never takes no for an answer.

A "turnaround" dance gives girls a chance to ask guys out, but that does not take any pressure off Cory, who now worries about who'll ask him, if anyone. Very unfortunately for Cory, it may turn out to be a dance abundant in rejection.
