Bar Bully
There's this little guy sat at a bar, when suddenly a thug smacks him and says "that's KUNGFU from Japan". Sometime later the thug again smacks the little guy saying "that's KARATE from Korea".
Well as you can well imagine the little guy was quite upset and hurt at this turn of events. So he leaves the bar only to return a short time later and smack the thug really hard, knocking him out cold. The little guy was quite please and turned to the barman saying "When that idiot wakes up tell him that was a shovel from B&Q."
