I myself have never really met anyone famous, but seem to know a lot of people who have. The closest I have ever come to meeting one was when Norv Turner (formerly a Redskins coach, now somewhere else but I forget where) nearly ran me over in a mall parking lot
My boyfriend's sister has interviewed Joan Jett and Dave Grohl. Also one of his other sisters was good friends with a pro football player's daughter (but I forget his name, you can see I know zero about football... he was pretty famous though... he's the one that drunkenly said something stupid to Sandra Day O'Connor) so they all knew him. My dad met Christian Slater on a plane, and the band Korn in an airport. And I don't know if this counts, but my grandfather knew the guy that Mel Gibson played in "We Were Soldiers" because... well, that was his unit in Vietnam. Oh, and one of my roommates in college's fiance is a cousin of Michael Tucker, a lesser-known pro baseball player. Also a good friend of mine is Greg Maddux's (sp?) cousin.
Maybe one day I'LL actually meet someone famous
