A little 50-year old Canadian man is minding his own business at a bar, drinking his beer when a big burly American walks past him, and hits him on the neck, sending him sprawling to the floor.
The big bully looks down at the Canadian, and says, "That's a karate chop from Korea!"
The Canadian climbs back onto his barstool, and continues to drink his beer, until the American walks by him again, and hits him on the other side of the neck, sending him back down to the floor.
"That was a judo chop from Japan!" the American grins.
The Canadian has had enough and leaves, only to return a half hour later. He walks up behind the American, whacks him on the head, knocking the bully to the floor, unconscious. The Canadian tells the bartender,
"When he wakes up, tell him that was a hockey stick from Canada!"
