This is actually a very old video from 2004 and I don't know if it's been posted here (didn't bother to check). I just thought I'd share with you all since it's pretty awesome.
The video shows an incredible fight between some random guy (using Chun-Li) and Diago (using Ken).
"You won't see moments of game mastery like this very often."
Edit- Oh here's the old thread
Still pretty cool nowadays imo.
