So I hear that Pride has been under suspicion for working fights on here all the time. The best one that I've seen, and I'm talking best finish was Takada vs Otsuka in Pride 7 I believe. It was pretty much a pro wrestling match with a few running drop kicks, suplex, Otsuka getting a nasty rope burn on his arm from horse playing and the finish. Takada kicks Otsuka in the chin from the guard and Otsuka does a 360 spin with his arms spinning like a helicopter, then hits the ground. Takada gets up and kicks Otsuka in the stomach (while he's laying there like a dead fish), rains down punches, then chokes him out even though he was clinically dead 3 minutes ago. Frick'in crazy! If you haven't seen this, it's definitely worth a watch.
The second best worked fight would be Rickson vs Royler with their jjjjjjuuuuuu-jjjjjitsu demo in an earlier Pride!
