Not at like an expo though. Guys you've met in a gym or just out and about. Ken Shamrock. Met him while I was in the Marines. He was super nice. He was actually there as a guest showing us some self defense tactics. (Yes I'm old because this was years ago). Anderson Silva- nicest fighter I ever met. I didn't say much to him but just asked to shake his hand. He was very kind and took the time to shake the hand of everyone there and was all smiles the entire time. Big Nog - also very nice. I could actually communicate a bit with him which was cool. He was also very nice to my demon of an ex wife even though she didn't care about mma and didn't know who he was. Andre Galvao- this one was different because for a time I trained at ATOS so I'd see him quite a bit. He is a very nice person though. Has a good sense of humor and the absolute best guy I've ever rolled with, hands down. Cris Cyborg- also very nice. Saw her at a restaurant. I'm not a douchebag so I didn't bother her while she was eating, but when she left I just asked to shake her hand. Royler Gracie - this was when I trained at Gracie Humaita. So I met him multiple times. He was always friendly and funny. I have a great deal of respect for the Gracies so I didn't really talk his ear off. Just thanked him for the work him and his family have done and shook his hand. His bjj knowledge is freaking amazing, but that goes without saying. The only person I met that was kind of a dick was Josh Burkman. I don't really hold it against him though because he seemed like he was in a hurry. I don't ask for pics or autographs, but ask to shake their hands. Josh shook my hand but said "no autograph" when I hadn't even asked him for that. There are a few more lesser known fighters that I've met just from years of bjj training, not to mention big names in bjj that didnt really ever do mma, but that I was stoked about meeting, but these would be the biggest ones. Any experiences you guys have?
