Drainage.

SPOILER ALERT...If you have'nt seen the movie, don't watch this clip, but I knew from the minute that this scene started that this was going to be one of the greatest scenes in cinematic history. It's not the whole thing, but damn. The Oscar was more than well deserved for this one. I mean, this guy even walks a certain way the whole movie not to mention he has to beat the hell out of about 4 people (and they were all real beatings I guess) over the course of the film. Definitely in my Top 3.
