He didnt knock him out..hes laughing.
Im pretty sure the guy is pissed, they werent particularly strong punches.
And drunks are pretty easy to knock down anyway.
Still Sadlad is right, these east european bums are becoming a problem, they are alot tougher than our usual lot.
doesent take strong punch to knock someone out. but that punch from the bum sat that dude on his ass. his knuckle probly poped him right in the eye socket, lol
