Rare and unusual but there really is some German language comedythat's actually funny.
Heres two Austrians (Stermann and Grissemann) who like to take the piss out of the Germans, very funny chaps, but only if you can understand German.

This is GREAT though, animated Hitler in his bunker song, finally translated to English, though the original German version is better.
