A teacher asks a group of ten year olds to tell a story to the rest of the class that has a moral.
Little Johnny (the rough kid in the class) get's up and says "Well miss, my grandad was in the war and one day he was caught on the german side of the trenches and he only had a bottle of whiskey and his big knife. He drank the bottle of whiskey and then killed about a hundred germans and then after that his mates rescued him"
The teacher, looking puzzled says "Oh, that's really great Johnny, a bit violent but really great. But what was the moral"
Johnny looks up and without skipping a beat says...
"Never, ever F**k with my grandad when he's pi$$ed!!"
Ithankyou!!!
