The little guy

There was this little 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 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 returned. Without saying a word, he walks up behind
the big dude and -- WHAM!!!" -- 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's a crowbar from Sears."
