Sledgehammer

A midget is sitting in a bar. In comes this giant 6'4" guy. He takes the midget and beats the shit out of him and knocks him out cold. He tells the bartender, "When he wakes up, tell him that was 'Karate from Korea.'"

The next night, the same midget is sitting at the bar and in walks the same big guy. He goes up to the midget and beats the shit out of him again. He says to the bartender, "When he wakes up, tell him that was 'Judo from Japan.'"

The next night, the big guy is sitting at the bar and the midget walks in. This time the midget beats the shit out of the guy and says to the bartender, "When he wakes up, tell him that was a sledgehammer from Sears."
