The Big Bang Theory

Recap

After Leonard ruins regular guys for Penny, she comes over to his apartment after a bad date with a moron for some drunken sex with Leonard.  The poor guy takes it as a sign she wants to get back together, but she breaks his fragile little heart again.  He heads over to Leslie's for a booty call, fails, heads back to Penny's for one and fails again.

Meanwhile, Raj and Wolowitz create an online dating profile for Sheldon and it finds him a perfect match.  They blackmail Sheldon into going on the date where he meets the female version of him: Amy (Mayim Bialik).
