Chuck Bartowski, our favorite TV nerd. Actually, don't let the nerd tag fool ya Chuck, as played by all-kinds-of-yummy actor Zachary Levi, is a nerd, but a very adorkable nerd. In fact, he's the leader of the Nerd Herd, the Geek Squad-ish computer experts who work at the fictitious Buy More superstore. But, through a fluke that later turned out to not be an accident at all, Chuck's big brain was filled with a computer download of the U.S. government's top secret spy info, meaning Chuck had to be recruited as an undercover spy himself. That has led to some dangerous and hilarious missions for the fake 007, as well as a crush on his beautiful spy handler, Sarah. He's also got a nerdy sidekick/BFF, Morgan, who's good for more than a few laughs; some quirky Buy More co-workers; and a sweet sister who's engaged to a doctor who's so smart, handsome and nice that the gang affectionately refers to him as Captain Awesome.
