I lived in Napa, CA and worked in some rather nice restaurants. Also, I worked with one of the Grateful Dead's former accountants. I have met quite a few famous people, partied at their homes, even had one very famous actor get drunk enough in my living room to pass out and pee on my couch.
Those I have partied with include Lars Ulrich (I played his drums!), Jerry Garcia, Gwen Stefani (before she was famous) and Nick Cage.
I waited on Willie Mays and Willie McCovey once together for the afternoon and got them both to autograph a Giants cap for my father. I risked getting fired for that one and unprofessional as it might have been, will never regret it.
Robert Downey, Jr. walked in on me and his girlfriend's kids' baby sitter "enjoying" his hotel suite's whirlpool tub once.
Many cool stories. But I am related to absolutely no one famous, that I know of.
