I was in Tomorrowland, Disney World a few years back and see Chad Johnson (OCHO Cinco) sitting on a bench. We looked at each other. I then went over to the bench he was sitting on and sat down right next to him and kept it low key, ''You're OCHO right?'' He nods, I shake his hand, asked for an Autograph, he did, I thanked him, he nodded again.
A couple years later, I was on Carousel of Progress, and a guy behind me starts laughing and scoffing at the ride, and he has a steelers shirt on. I thought he looked familiar. When I exited, I waited for him , shook his hand and said ''You're Kevin Greene'' YES i am, he says, big smile. I said you belong in the hall of fame (at the time, he wasn't) He said he appreciated that, and asked if I played any ball? I said no. He said ''Shame, you're certainly the size for it'' He was friendly and it was a cool moment.
My dad got me an autograph of Jack Palance on a disney hat in MGM back around 96' , and in the early 90's my dad and I met Hank Aaron to sign a ball.

I'm trying to meet Axl Rose. I'd pay good money for a signed Axl GNR translight. That's a pretty tough one.
