The Big Bang Theory is a sitcom that shows what happens when hyperintelligent roommates/physicists Sheldon and Leonard meet Penny, a beautiful woman moving in next door—and realize they know next to nothing about life outside of the lab. Rounding out the crew are the smarmy Wolowitz, who thinks he’s as sexy as he is brainy, and Koothrappali, who suffers from an inability to speak in the presence of a woman.
