A redneck is sitting in a bar drinking minding his own business when a large asian man goes over to him and knocks him off his chair. He then tells the redneck, " That was a karate chop from Korea." The redneck is mad but he gets up and goes back to drinking. All of a sudden the asian man knocks him over again and says, " That was a judo chop from Korea." The redneck is real mad now so he leaves and comes back an hour later. He goes over to the asian man and knocks him off the stool knocking him out cold. He turns at the bartender and says, " When he wakes up tell him that was a crowbar from K-Mart."
It's funnier as a Dwarf/Midget/Small Person (depending on which you find funniest and least offending) knocking out the big person. But about the redneck, everyone knows that after the first hit the drunken redneck would have got into a brawl with the guy and probably cut him with a broken beer bottle, if not going, he would go out to his truck and get his shotgun and fill the big guy with buck shot. All that being said, I enjoy all forms of this joke.
