So a grandfather sees his 20 year old grandson playing X-Box and says: "Hans, why do you not go out and have fun? I did at your age."
Hans says "okay, where should I go?".
Grandpa Fritz says "when I was your age I went through Paris and went to many nightclubs, drank all night, banged the dancers, went wild, and didn't even pay!"
Hans thinks this sounds awesome. So he goes across the border to Paris to have some fun. A week later he comes back and is covered in bruises and cuts.
"Mein Gott," says grandpa Fritz. "What happened?"
Hans says "I went with my friends and did all those things you did once but the club bouncers beat the hell out of me and I got jailed for the night."
Grandpa goes: "You went with your friends?"
Hans goes: "Yeah, and they were no help. Who did you go do all these wild things with?"
Grandpa; "the SS!!!"
