Gestapo Joke
A : Have you heard the gestapo joke?
b : No...
(A slaps B hard around the around the face and shouts in a comedy Nazi accent)
A : Liar!
If the question is answered with a weary "Yes", then slap them and call them a liar anyway; disorientation is a perfectly valid method of interrogation.

After reading this joke and finding it to my great liking, I told it to my mum in a Little Chef.
I didn't slap her, but I did shout 'LIAR!' in a very authentic manner. A family were walking past our table on their way out as I said it, and they all jumped. They must have thought it was a Nazi domestic.
