There was a wee lass sitting at the bar, a big thug walks up to him and hits him, he says; "That's a karatti chop from Japan!"
The same thug walks up to him and hits him again and says; "That's a karitti chop from Sout Karea!" The wee guy goes out and later comes back and hits the thug out cold! Then says to the barman; "When that big B***ard wakes up tell him; that's a crow bar from B&Q!"
How cool my brother taught me this when I was 12.
