The Big Bang Theory

Mensa-fied best friends Leonard and Sheldon may be able to tell everybody more than they want to know about quantum physics, but getting through most basic social situations totally baffles them. How lucky, then, that babe-alicious screenwriter/waitress Penny just moved next door. Will worlds collide? Does Einstein theorize in the woods?
