There was this short guy sitting in a bar, drinking his beer, minding his own business when all of a sudden this great big dude comes in and - WHACK!! -- knocks him off the bar stool and onto the floor.

The big dude says: "That was a karate chop from Korea."

The short 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.

This time he says: "That was a judo chop from Japan."

So the short guy decides he has had enough of this. He gets up, brushes himself off and quietly leaves. An hour or so passes when he returns to the bar.

Without saying a word, he walks up behind the big dude and - WHAM!!!" - knocks the big dude off his stool, putting him out cold!

The short guy looks at the bartender and says: "When he gets up, tell him that was a crowbar from Sears."
