The Big Bang Theory is an American sitcom currently in its third season on CBS. The show centers around two Caltech physicist roommates: Leonard and Sheldon. Leonard, the more socially adjusted of the two, carries the emotional arcs of the series, often showcasing his on-again-off-again relationship with his attractive neighbor Penny. Sheldon, the breakout character, appears to have either an autistic spectrum disorder or Asperger syndrome, but in a fun way. The show balances typical sitcom plots with funny characters and clever, geek friendly humor.
