NBC's Chuck is described as a "computer geek by day. Government operative by night." Zachary Levi, who plays Chuck (and is one of our 8 Hottest Guys on Fall TV), tells us his favorite part of playing a secret (clueless) agent man. Surprisingly, it has nothing to do with hot babe guest stars like Rachel Bilson. Hint: it has something to do with the word "Chuck." Go figure!
Premieres: Monday, Sept. 24, 8 p.m. ET
