Wee guy sitting at the bar, a big thug walks in and hits him to the floor and says thats a karate chop from Korea. Later the thug walks up to him and hits him again and says thats a judo chop from Japan. Wee guy goes out and few minutes later returns, smacks thug on the head and knocks him out cold and says to the barman, when that b@st*rd wakes up tell him that was a crow bar from Halfords.
