3x13 - Undressed

Cindy has a crush on popular Billy so she buys him in the high school "slave auction." She then asks Stephanie to trade slaves with her so that Stephanie can ask Billy questions and report back to her. Stan enlists Lena to help him find the mystery woman he drunkenly got together with at a party -- the one who occupied a leopard skin bra that was left on his bed. While finishing up a project late at his place, Janice and Carl decide to mix work and sex.
