Tony Dorsett when I was about 11. He was signing autographs at a Lee (jeans) event. He tried to speak with me several times when it was my turn for an autograph, but this guy was my idol growing up..... and I literally couldn't even muster a "hello".... I still laugh about it to this day. I was completely in awe.
Troy Aikman..... a benefit for some charity. You could tell he didn't want to be there, but he was friendly enough. Much, much larger in person that I would have guessed. Huge hands.
Dave Campo.... same event...... nicest guy I ever met in my life. He offered to let me wear his Super Bowl ring. Absolutely could not have been nicer if you paid him.
Emmitt Smith..... At a bar. Spoke a couple of words with him, but he had no interest in talking really. My wife sat down at his table and talked with him for 5 minutes or so.
Micheal Irvin....funny story....... saw him at a hooters and he was walking by my table to go to the restroom. I looked up, and our eyes met. I said "Hi, Michael"...... and he looked at me like I was pond scum. So knowing that he had to go back the same way he came when he was done in the restroom, I poured out several nutrasweet packets on the table and made lines out of them to look like cocaine..... when he came back my way I said...."Hey, Michael.....want to join us"...... He just kept walking. Spoke with a couple of the waitresses there and she said he was a complete jerk and the girls get in arguments about who has to serve his table because none of them want anything to do with him.
Joe Avezzano.....don't know what it is with that guy, but I used to run into him all over town. I must have crossed paths with him 6-8 times in a 2 year period. Real nice guy though. Always took the time to talk to everyone.
There are a few more, but no exciting stories.
