A couple years ago I met Tiger Woods in a hotel elevator in Las Vegas! It was pretty cool, he was a very nice guy. I didn't even know it was him until he got off the elevator! Still, it was awesome!
I also met John Stamos (Uncle Jesse in Full House) when he was on Broadway in How to Succeed in Business Without Really Trying. He was also a really nice guy!
That's about as close as I've gotten to fame!
