The deaf would have complained
A supply teacher took a music lesson of 4th year seniors that consisted of the class (approx 30) being split into pairs, each with a keyboard set to a different instrument and a piece of music to play. The effect should have been of an orchestra playing something wonderful. However I couldn't be arsed to partake in this so when the teacher started us off I kept playing all the right notes, but not necessarily in the right order.
Most of the other groups had the same idea so the swots and musically enthusiastic kept time and played well, the rest of us mashed the keyboard like Steven Hawking having a sneezing fit. She got each pair to play individually (which we did properly) and couldn’t work out why it sounded like a Jack Russell being raped by a Gorilla when we all started together and after restarting the piece for the 8thth time was almost hysterical and screamed at us “This was written for 6 year olds to play!”
The noise was so offensive that the head of year (who was teaching in the next room) came in and gave us an almighty bollocking and threats of detentions for a fortnight. He then stood at the front of the room and said “GO”. Funnily enough we were all note perfect.

I think you were just playing Stockhausen without noticing it
"mashed the keyboard like Steven Hawking having a sneezing fit" alone is worth a click. But if we had had 15 keyboards I think I would have been more motivated than I was being the 5th guy in our class who could play the piano quite well, but had to make do with percussion as there was only one piano. That seemed like a good excuse to mess around, but even the possibilities for getting anything wrong were so few, it got boring after three minutes.
