A boy was upstairs playing on his computer when his granddad came into the room and sat down on the bed. “What are you doing?” asked the granddad. “You’re 18 years old and wasting your life. When I was 18 I went to Paris, to the Moulin Rouge, drank all night, had my way with the dancers, pissed on the barman and left without paying. Now that’s how to have a good time!” A week later, the granddad comes to visit again. He finds the boy still in his room, but with a broken arm in plaster, two black eyes and missing all his front teeth. “What happened?” he asked. “Oh granddad,” replied the boy. “I did what you did. I went to Paris, to the Moulin Rouge, drank all night, had my way with the dancers and pissed all over the barman – but he beat the crap out of me!” “Oh dear” replied the granddad. “Who did you go with?” “Just some friends. Why? Who did you go with?” “Oh” replied the granddad. “The Third Panzer Division.”
