Smallville :

Still guilt-ridden about the destruction he caused while he was controlled by Zod, known as 'Dark Thursday', Lex throws a charity costume ball for the town and hires The All-American Rejects (playing themselves) to perform.

Lois reluctantly agrees to be billionaire Oliver Queen's date to the event. Meanwhile, Clark and Chloe pursue a female creature, Gloria a park ranger, that plants seeds in male human bodies in order to procreate, and the hunt intensifies after the entity attacks Jimmy.
