A huge burly guy walked into a bar. As he passed a meek little man sitting at the bar, he hit him on the neck and knocked him to the floor. The big guy said, "That was a karate chop from Korea." The little man eventually climbed back up on his barstool. Soon, the big guy headed for the bathroom and, as he passed the little man, he hit him on the other side of the neck and knocked him to the floor again. The big guy said, "That was a judo chop from Japan." The little guy had had enough. He left, but returned a few minutes later, walked behind the big burly guy, conked him on the head and knocked him to the floor. The little guy said to the bartender, "When he wakes up, tell him that was a crowbar from my car!"
