I've only met two and you've probably never heard of either of them. About a decade ago, I went to a martial arts convention called "Dragonfest". I met Don 'the Dragon' Wilson, probably mostly famous for the "Bloodfist" franchise and even got a photo with him. I remember he was talking to some guy and he kept name dropping himself a lot, which was...odd...But he had no issue taking a picture with me and unlike a lot of guys there, he didn't charge any money. I also met Fumio Demura, whose mostly known for his stuntwork than his acting. He's probably mostly famous for being Pat Morita's stunt double in "The Karate Kid". He is actually the one you see doing the Crane Kick. He did appear in some movies though, such as "Ninja" with Scott Adkins. At that same con I recognized a few others, but didn't actually approach them. The thunder guy from "Big Trouble in Little China" was charging $40 per autograph and I was too poor for that. Vince/Virgil from WWF/WCW was there and even though I was a huge wrestling fan at the time, I thank God I didn't seek him out as I hear he's prone to ripping people off. He was much bigger than I expected him to be though. The big star was the main bad guy from "Mortal Kombat", but too many people were swarming him so I only saw him from a distance. His hair cut at the time was bizarre. Anyway, nothing impressive from me. But have you met anyone who counts as a 'celebrity' in any way, shape or form?
