19. JON HAMM
Before Jon Hamm guest-hosted Saturday Night Live on Oct. 25, most people would've been surprised to learn that he's a self-professed ''huge comedy nerd.'' But by the time the 37-year-old Mad Men star busted out ''Jon Hamm's John Ham: the ham you can eat in the bathroom,'' it was clear that the real Hamm is forgive us a real ham. And then there's the simmering intensity he brings to Don Draper, 1960s Madison Avenue adman extraordinaire, whose dark and mysterious life took an even darker and more mysterious turn this year on the critically acclaimed AMC drama. Says Hamm, ''It would be the most boring thing in the world to play a guy who's just nice to everybody and only pets puppies and makes soup.'' Ari Karpel
