Alice Cooper: Crossroads Mall 1991. I was working at Software Etc. (How's that for a blast from the past?) It was a Sunday so the store was slow and he and one of his 'crew' came in. He was looking for a game (can't remember which one). He came up to the register and I kinda mumbled out, 'Hey...you're Alice Cooper.' He just looked at me and said, 'Yeah man, I am.' Talked for a few minutes. Really nice guy  

The rest of them were from various trips to Vegas. 
Jenny McCarthy - sat at a Blackjack table with her and played a few hands. (Mid 90's)

Pierce Brosnan - Walking through the MGM. Had a full entourage of people with him. Shorter in real life than I was expecting. (Mid 90's)

Cheryl Hines - (From Curb Your Enthusiasm) In an elevator with her at the Palms. Really nice lady. (Early 2000's)

Crystal Bernard - lesser known from a show in the 90's called Wings. Saw her sitting alone at a Black Jack table in the MGM. She wasn't playing (table was closed) and was just sitting there. I kinda thought she was cute so I approahed her and said, 'Are you Crystal Bernard?' She stuck out her hand and said, (in her southern drawl) 'Yep. What's your name?' I shook her hand and said '[m0resn0w]. Nice to meet you. I'm a fan.' (Yeah, I know...cringe.) She was also really nice.
