Hallo aus Berlin madness #1 - Song from Schule (kunst.wav)

All my mates and I, had this as a .wav for a long time.. before finding out the full reality of the insanity behind Hallo aus Berlin. Superb.
Serenading the students watching this with a 1 minute long banging intro before any lyrics happen == amusement.
Also not sure what some schoolboy is doing hugging a girl in class with his trousers around his ankles?? :S
