Athlete-wise, I have a few...used to talk to Nate Newton some when I lived in Dallas - his best friend (ironically, a cop) lived below me in my apartment complex. I always seemed to run into him when I was headed out to play basketball - he ALWAYS commented on it.
I was at a party with former Cowboys player Crawford Kerr. What a complete tool.
Ran into Scott Skiles and Jeff Turner out in Dallas after a Orlando Magic-Dallas Mavericks game.
I played with a cover band at the Dallas Cowboys' Christmas Party one year - Emmitt Smith was one of the only players who paid any attention to us.
Stood next to Lisa Leslie at a club inside The Forum back in the day; yep, she's tall.
The late Roy Tarpley was on a flight I was on.
Was on another flight with Dick Enberg and the guy formerly-known-as Bruce Jenner.
I used to go to the L.A. club Roxbury (yeah, THAT one) when I lived in L.A. Some idiot girl thought it would be fun to try to pit Charles Barkley and I against each other...tried to make both of us jealous of each other...didn't work.
And as evidenced by my profile, I did play in a band for Roger Goodell's wedding in Chicago. Didn't really know who or what I was playing for, but looked up from my music stand at one point and saw Paul Tagliabue staring back at me.
I've got a few celebrity stories in my past - Jay Leno, Cynda Williams, Laura Linney, Quincy Jones, Spike Lee, Van Morrison, Ross Perot, Linda Evans, Yanni, Cab Calloway, Dolly Parton, Regis Philbin, Al Sharpton, Sharon Stone, Geena Davis, Julia Roberts, May Britt (I knew most of Sammy Davis Jr.'s family), Michael Beach, Eriq La Salle, Michael York, Shannen Doherty, Chuck Berry, Betty Ford, Shiela and Meredith MacRae, Carmen Electra, Harrison Ford, Douglas Adams (Hitchhiker's Guide to the Galaxy), Pete Barbutti, Chad Everett, Jasmine Guy, Lou Diamond Phillips, David Ogden Stiers, Ann Landers, and Dave Chappelle.
There might be others...some of the above stories are interesting; some are just random run-ins.
