Even as a joke, don't. The Germans do not find it humorous. I recall a story of a British professor being arrested for doing something similar in a German airport.
It's actually illegal here to use Swastikas or Nazi salutes. Nazi paraphernalia isn't allowed on flea markets or Ebay, and the original version of Wolfenstein 3D is banned.
You're also not allowed to insult police officers, including flipping them the bird, which would net you a fine.
Never been to München/Munich so I can't recommend anything, besides visit some public transportation to hitch a ride to Berlin. Fortunately for you, legal drinking age for beer and wine in Germany is 16, so you could taste-test some fine German beer. Unfortunately for you, well, the "school-sponsored" part.
