My mom's ex-boyfriend (whom I knew well), was 1st cousin's with Lee Majors (star of the TV show "The Fall Guy" & "The 6 Million Dollar Man").
The mother of one of my childhood friends, used to date this actor guy for many many years, and I knew him, and he me. His name is Dennis Neal. He played the black detective (sidekick of Kevin Bacon's? or Matt Dillon's, I forget) in the 1998 movie "Wild Things", name was "Art Maddox" (just looked it up), was a big enough role to remember the character. And Matt Dillon, Kevin Bacon, Neve Campbell, Denise Richards, etc. played in that movie. I'm assuming he knows some of those people =)
Oh, and Rob Thomas, the lead singer of the band "Matchbox 20" went to my high school, but not while I was there. He did know my sister I believe, and definitely knew (and used to smoke pot with, or so he claims) one of my sister's good friends. Also, my 1st cousin has a good female friend that I know, and she used to watch the lead singer of Creed play basketball (she had a crush on him, they knew each other), before they were a band I think.
Those are about the only links that come to mind immediately.
Oh, and Jennifer Love-Hewitt and I are psychically linked, and will one day be married.... I know she can feel it too, so she does know me, but she's just ignoring it for now =P Lots of other hot female celeb's I have these links to as well, none have responded yet.... I don't see how they can fight the urge...
