There have been plenty of breakout talents in the history of Saturday Night Live, but few have gotten us breaking out of our boxers like Tina Fey. It’s more than just the eyeglasses that make her a brainy beauty. Tina actually made her transition to the show’s cast as the first female head writer in the history of SNL. She seldom appears outside of anchoring the regular Weekend Update unless there's a shortage of women for a sketch, but that's enough for Tina to keep us up as our favorite weekend date. She knows how to use her sharp sexy look, too, as seen by plenty of alluring photo shoots and her absurdly sexy role as a high-school teacher in the hit comedy Mean Girls (2004)--which, typically, Tina scripted herself as an adaptation of the non-fiction book Queen Bees & Wannabes: Helping Your Daughter Survive Cliques, Gossip, Boyfriends, and Other Realities of Adolescence.
