A little guy in a Bar

[cam]

A little man walks into his favorite bar and sits down to order a
beer.He gets his beer and sits at the corner of the bar, quietly drinking his
beer. A huge (Bubba Smith-type) guy comes in and sits next to him.
All of the sudden the big guy turns to him and - WHACK - knocks him
clear off the bar stool, across the floor, and up against the back wall.
The little fellow doesn't know what hit him. He picks himself up
and walks back to his bar stool and sits down. He turns to the big guy
and says, "What on earth was that for?"
The big guy replies, "That was my karate, from Korea."
The little fellow thinks: Well this guy's wacko. I'm going to finish
my beer and get the hell out of here.
But all of a sudden the big guy turns on him again and - BANG - knocks
him off his bar stool, across the floor, up against the back wall. Again the
little fellow doesn't know what hit him. He picks himself up and figures that
the big guy is definately wacko. Returning to the stool for his beer, he
asks "What was that for?"
"That was my judo from Japan," replies the brute.
The little fellow has had enough, so he leaves the bar. About a
half hour later the little fellow peeks his head into the bar and sees the big
guy still sitting there. So he tiptoes up behind him and goes - WHAM!
The big fellow is out cold.
The bartender walks up to see whats going on, and the little fellow
looks at the bartender and says, "When that son of a bitch comes to, you tell
him that was my crowbar from K-Mart."
