Archival sources, including school inspector reports, reveal that Bach’s education was troubled by gang warfare and bullying, sadism and sodomy – as well as his own extensive truancy…documents damn the boys as “rowdy, subversive, thuggish, beer- and wine-loving, girl-chasing … breaking windows and brandishing their daggers”. He added: “More disquieting were rumours of a ‘brutalisation of the boys’ and evidence that many parents kept their children at home – not because they were sick, but for fear of what went on in or outside school.”
I guess Bach was a teenage thug, though that seems like it was pretty par for the course back in the day. Also, Mozart apparently loved scatological humor as seen in this beautiful letter to his cousin:
Well, I wish you good night
But first shit into your bed and make it burst.
Sleep soundly, my love
Into your mouth your arse you’ll shove.
