What was the coolest fight you ever saw live?
Personally the entire round of Fedor vs. Hendo was unreal, nobody sat down the whole time.
Lytle stuffing Hardy's takedown and then securing the choke was another super loud moment
A grandmaster from China VS 2 dozen fighters from my school (each with at least 7 years training, we wore no colors on our sashes). Thankfully I was injured and was not one of them.
Anderson Chael 1 
UGCTT_warjimmiller - Anderson Chael 1
This.
Freeman vs Mir
The entire Pride 33 card. Diaz/Gomi, Thierry/Lil Nog, Shogun/Overeem, Hendo/Wandy, plus Chuck Norris was there... 
Leben vs Akiyama was a lot of fun
creppy joe vs varner
Fedor Arlovski
Shogun Machida 2.
Diaz vs BJ
Of the two events I've gone to
Cruickshank vs Martinez
Marquardt vs Woodley
I got to see Anderson win the title live. I also saw Dan Henderson vs Wand and Diaz vs Gomi when Pride came out here.

Nigel Benn vs Gerald McClellan was a war and when i watched it i got totally caught up in the moment, only afterwards did i realize what happened and i felt guilty afterwards
Lawler vs Manhoef fight wasn't crazy but the finish was.
