I'm not related to anyone famous to my knowledge. I have met a few people though.....
Kevin Smith (no, not Silent Bob
, but the actor who played ARES, God Of War on Xena, and is now deceased R.I.P.)
Hudson Leick (The woman who played Callisto on Xena)
Robin Quivers (Howard Stern's "sidekick")
Antonio Banderas
I also attended a taping of Conan O'Brien in October when I was in NYC. His guests that day were Lucy Liu & Michael Moore. I'm a HUGE fan of both people and I had no idea they'd be the guests. I just wanted to see Conan, but that was a special treat!
EDIT: I forgot, I also met some people from Farscape & Star Trek Voyager at a convention for fantasy/sci-fi shows, but I honestly forget who they are because I don't watch those shows. I was there for the Xena actors
. The chick from Farscape played a bald blue alien. That's all I remember.
