I took AP music theory classes, as an outsider, it was mostly just an extra music class for the band geeks, but I'd been playing guitar and piano for years already by the start of high school. Four years, and the band geeks were always the most degenerate, depraved burn outs I've ever seen in my whole life. I did some partying in college, but none of it compared to the shit these high school kids had been doing since they were freshmen.
I teach AP music theory now, and it's the same thing, a class that pretty much exists just to make these burn outs pretend to be academically inclined. They always, always, always come in smelling strongly of weed, and three times, now, have I witnessed girls trying to sneak hand jobs to boys, or boys trying to sneak finger blast girls. Last time I saw something to this effect, there was a girl in the back of the class, sat between two boys, and she was going skiing. There's no reason for a grown man to be seeing this much teeny bopper cocks, no siree.
