There was this little guy sitting on a stool in bar drinking, minding his own business, when suddenly this big guy came in and walked over to him. WHACK!! knocked him clean off the bar stool unto the floor. The big guy said, "That was a karate chop from Korea".

The little guy thought, "GEEZ", but he got back on the stool and bought himself another drink.
Then suddenly, WHACK!! the big guy knocked him down again , and said, "That was a judo chop from Japan".
The little guy had had enough!

He got up, brushed himself off, and quietly left.
After about a hour, he returned.
Without saying a word, he walked over to the big guy, who was now sitting at the bar and, BONG!! banged him clean off his stool, knocked him out cold.
The little guy turned to the Bartender and said, "When he comes to, tell him , that was a Crowbar from Sears".
