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

The
idiot 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."

So 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!!-- bangs 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 is a crowbar
from Sears."
