This is personally my favorite fight scene ever in a movie. It comes from the movie Dumb and Dumber.

The fight scene in Bourne Ultimatum is the best I've seen so far. Spoiler: Jason Bourne wins!
I'd like to nominate the fight scenes in 300.
Happy Gilmore v. Bob Barker?
i'm a big fan of the Jackie Chan vs Benny the Jet fights from way back when Jackie wasn't a joke.

Bruce Lee vs Kareem.
Bruce Lee vs Kareem.
For me, it is Bruce Lee vs the entire Japanese Bushido school from "Fist of Fury" (1972)
Don't forget Jet Li vs the entire French police martial arts class in Kiss of the Dragon.
This is a good fight scene. A guy whom I knew in Special Forces told me that this is the most realistic movie fight scene he ever saw.

Yeah that's Benny the Jet. I posted his classic fight against Jackie Chan earlier.
My favourite brawl is the bathroom scene from The Warriors: http://youtube.com/watch?v=ISkLxfAOTo8
Man, that brings back memories! Great flick. WAAAA-riors!!! Come out to PLAY-YAY!!!
I think the best fight scene that "never was" was in Raiders of the Lost Ark (1981) -- that guy's sword vs. Harrison Ford's gun -- http://www.spikedhumor.com/articles/118234/Indiana_Jones_Sword_vs_Gun.html
Most entertaining fight scene? The knight vs. the giant in Monty Python's "Holy Grail." "It's just a flesh wound..."
THE BEST fight scene ever is in the French movie, District B13 (Banlieue 13 in french) Whatch this and you'll see what i'm talking about. Kick butt fight starts at about 1:45
