BRETT FAVRE Anyone have a tissue? The former Green Bay Packer (...and New York Jet... and Minnesota Viking...) has retired more times than Hulk Hogan, and each time he's announced his retirement, he ends up trying to talk through another tidal wave of tears. While not the manliest thing to do on camera—repeatedly—Favre won't have a problem watching you cry like a baby when his 6'2", 220-pound frame does a touchdown dance on your spine.
ROBERT DOWNEY JR. He had the worst '80s fashion sense, he's gotten so high he broke into a neighbor's house and fell asleep in a stranger's bed and he used to star in Ally McBeal. Pushover, right? Wrong. Today's Tony Stark is so well-versed in Wing Chun that he left his stuntmen bloodied and battered while working on the set of Sherlock Holmes. You'd be making a mistake to think that the 5'8" actor isn't afraid to throw hands. Just take comfort in knowing that he'd probably say something witty as he broke your nose.
MIKE TYSON With his penchant for pigeons and his soft-spoken demeanor (not to mention a disastrous stint on Dancing With the Stars), you'd never guess this is the same guy who could knock your head clean off with one uppercut. “Iron” Mike Tyson was the most dominating force in boxing for years, but has moved on from his life of violence toward helping others and keeping his pigeons well fed. But that's not the sound of bird droppings on your head if you step to the former heavyweight champion of the world, it's the sound of Tyson dropping knuckle bombs on your face.
