For some reason, this reminds me of a story my dad told of being in college in the early 70s. Apparently there was a "game" going around - a sort of viral joke - that involved going up to someone and in a terrible German accent saying "Do you vant to play Geshtapo?" and no matter what they said, slapping them (probably gently) on the face and saying "You lie! You lie!" - probably funnier 30 years after WWII rather than 80 years we are now. heh.
So he did this and it was fun until the one time he started to do it to one of the football players. Massive guy, not so quick on the uptake.... He said he went up to him, asked "Do you vant to play Geshtapo?" and started to put his hand up to slap him, and the guy grabbed his arm, looked confused and said, "What dis?" and my dad was like "Just a joke....... nevermind.........." lol. And that was the end of that!
(I suppose it's too late to mention that my dad is on the shorter and scrawnier side)
