Wikipedia's description: It concerns two 20-something prodigies; a theoretical and an experimental physicist at Caltech, who live across the hall from a blonde waitress with showbusiness aspirations; their geekiness is contrasted to her naïveté and common sense.
Very funny show. Lots of geeky humor. On any given episode you'll probably here several comic book, video game, and star trek jokes. I enjoy the show because many of the characters remind me of my friends. I won't name names but you know who you are.
The characters are:
Leonard Hofstadter - He seems to be the most normal of the four. He's in love with Penny across the hall and his roommate is Sheldon.
Sheldon Cooper - Easily, the best character on the show. He's a child prodigy. He has an inflated ego, social ineptness, and a lack of empathy. He fails to understand most situations.
Howard Wolowitz - Still lives with his mom and is constantly hitting on every girl he sees.
Rajesh Koothrappali - Is from India and has one small problem. He can't talk to girls unless he is drunk.
Penny - Is Leonard's next door neighbor. She usually has no clue what the guys are talking about.
Big Bang Theory airs Mondays at 8:00 PM on CBS
