Steve Martin
He's starred in countless movies—from 1979's The Jerk to 2009's It's Complicated—and made millions laugh out loud with his performances on Saturday Night Live. With his physical humor and "wild and crazy guy" routine, it's no wonder our audience loved it when Steve stopped by.

"Oh, I really didn't deserve that applause. I deserved much more," he joked after walking onto The Oprah Show stage for the first time in 1991.
