I just saw a video recently about Bruce Buffer getting in a fight with Frank Trigg on an elevator. I can't look it up right now because I'm on my phone, but here's the gist of it.
Trigg had just lost to Matt Hughes by rear naked choke. He, Dana, Bruce, and Mike Goldberg were on an elevator together. Frank started to ask Dana about when he was going to fight next when Bruce cut in and complimented Dana on his new watch. While Bruce's back was turned, Trigg hit him from behind.
Bruce turned around and was like "What the hell? You just hit me." And Frank made the mistake of asking .
"What are you gonna do about it?"
Bruce hit him with a quick 1-2 to the stomach, and they started brawling right in the elevator. By the ene of it, Trigg was in a rear naked choke for the second time that night.
When they arrived at their floor, there was a bunch of expensive stuff in glass cases (fancy casino place I think.) so Bruce let him go and was like "Hey. It's over. Let's all just calm down. Later he had to get stitches in his hand, but after that apparently they had a pretty good night.
I thought it was a pretty cool story. Really made me respect Buffer a lot more.
