I talked to a guy who is related to MMA. Not that he is some kind of super champion, but he trains a lot in the gym and has held more than 20 fights. And he said that the MC and Vinny fight scene was bullshit. Vinny wouldn't have left the room on his own feet. He was standing in front of Fuckface, face to face, at a very close distance and with his hands down. Fuckface would knock him out in a split second by punching or elbowing him in the chin. Vinny wouldn't have had time to not only get, but even reach for a gun.
