I don't follow UFC or MMA at all. A couple of years ago, some dude was in my chair for a meeting I was having at a construction site. All the trades were crowding in the office for some reason, and I ended up talking for a bit with the guy in my spot. He seemed nice enough.
Turns out it was George St. Pierre. He was there promoting one of his sponsors which was safety boots. I had no clue who he was or what he did, but for such a little guy he seemed pretty ripped. Got a photo with him since everyone else was doing it. Pretty quiet guy overall. I googled him after the meeting and I was glad I didn't say anything to tick him off!
