I used to play "Purple Rain" so much on the piano during my years in high school after school hours that I never need to play that chord progression ever again. I'd even sneak into the hall where the piano was located at, wait for the janitor to leave and lock up the front door. I'd know the alarm system wouldn't go on until several hours later so I could have the whole echoing building all to myself.

Some of my more embarrassing moments was however when I was banging "Scandalous" on the keys and screaming it in silly falsetto when the principal had still been in the building and came to drag me out of the building. She'd usually let me stay though.
