Crowbar from Sears
A little guy was sitting in a bar, drinking, minding his own business when a great big dude comes in and WHACK!! -- knocks him clean off the bar stool and onto the floor. Then he says, "That was a karate chop from Korea."
The little guy thinks "GEEZ," but he gets back up on the stool and starts drinking again when all of a sudden - WHACK!! -- the big dude knocks him down AGAIN and says, "That was a judo chop from Japan."
The little guy has had enough of this . . . he gets up, brushes himself off and quietly leaves. The little guy is gone for an hour or so.
When he returns, without saying a word, he walks up behind the big idiot and BONG!! -- knocks the big dude off his stool, knocking him out cold.
The little guy looks at the bartender and says, "When he comes to, tell him that it was a crowbar from Sears."
