Two socially inept physicists realize how little they know about the real world when a beautiful woman moves into the apartment next door. Sheldon (Jim Parsons, in his first Emmy-nominated role) and Leonard (Johnny Galecki) try their best to impress Penny (Kaley Cuoco), who helps teach them about life outside their lab. In the second season of this witty sitcom, the geniuses and their equally awkward pals continue their education about the non-geek population.
