I think my funniest story was when I was in St. Louis about to leave on my way back to Cincinnati sometime around '06. I had to stop off for gas and when I went inside to pay, who else was in there but Joe Buck. The funny part is that this was when he had the commercials going for Holiday Inn where the three dude fans got him to say "Swing and a miss" while they felt his voice. So, of course, there's two other customers in the gas station trying to do the same thing. Joe politely declined and as he was leaving I think he noticed the (crap)-eating grin on my face, so he said to me, "It was a good idea at the time."
I also met Gary Coleman at a Hard Rock Cafe when I was out in California some years back. Nick Lachey (and a few Bengals) two seperate times, both at Cadillac Ranch dowtown. Bengals owner Mike Brown at a Reds game while just walking up the steps to our seats. Angels owner Arte Moreno while at school out in St. Louis - his son was in my fraternity.
Oh, and does Bootsy Collins count? Def. met him at Bootsy's one night (shocking, right?).
