34. '30 Rock'
Alec Baldwin said it best: "You are truly the Picasso of loneliness." He has a point. Tina Fey's Liz Lemon is a single gal who spends her evenings playing Monopoly alone, working on her night cheese or watching the Lifetime movie My Stepson Is My Cyber-Husband. But Fey made her a timeless heroine, turning her SNL writers-room experience into the backstage antics at The Girlie Show, with a crazy-deep bench that included Tracy Morgan, Jane Krakowski and Jack McBrayer. And Baldwin chewed up the role of his life, turning what could have been a generic sitcom boss into the only man worthy to stand by Lemon.
