Apart from Jeff Hardy, Torrie Wilson and a few Scottish football legends, the only famous people I've met have been musicians...
Ryan McCombs and Tim King from Soil
Dark Tranquillity (Niklas Sundin done my old band's first album artwork which ended up not being released)
Efrem Schulz of Death By Stereo
Benji Webbe from Skindred
Ben Weinman of Dillinger Escape Plan
Matt Halpern of Periphery
Ian Watkins of Lostprophets
Brandan Schieppati of Bleeding Through
Dragonforce (Got into a post-gig VIP party thanks to the guys from Mendeed)
There are more but those are the ones that stood out to me. Also, bumped into John Campbell of Lamb of God on the street in Sheffield, but didn't even realise it was him until he was walking away. Also walked straight past Coby Dick of Papa Roach cause he was dressed up like a complete tit.
I met Tommy Wiseau yesterday at a midnight screening of The Room. He's just as stupid and weird in person. Phony as fuck and had an unsurprising ego. Only signed autographs or took pictures if you bought his overpriced merch and did a really short/rushed Q&A before the movie started and got the fuck out of there. also he was wearing 5 different belts on his pants.
i randomly ran into Al Pacino one time in Manhattan, was just crossing the street with one of my friends, when all of a sudden he screams "OH SHIT! ITS SCARFACE lmaoo.. he was great, even stopped to talk with us for a quick sec ..real classy guy
Biggest for me is probably Vince Carter(NBA player), when he was with Raptors. Funny thing, is that he got traded like 2 months after I met him(though when I met him,you could really tell he wanted nothing to do with Toronto)
