Ran into Georges St. Pierre on the street while partying in south beach Miami back in February. My friends and I go to school in Montreal and are huge MMA fans so we were absolutely starstruck, but nobody on the street seemed to recognize him. He was just hanging out with one big friend/bodyguard, and gave us some death-grip handshakes and a photo before skipping an enormous line to get into a club we were just turned away from.

Funnily enough, fighters tend to need even more security than regular celebrities on a night out, which is why I was so surprised he didn't have more of an entourage. You'd think that it'd be counter intuitive (since who in their right mind would want to mess with a professional), but plenty of drunks and tough-guys want to try their luck.
