Around the Horn
I was in junior high/high school band for 5 years and never learned to read sheet music. I played trombone, so it was pretty easy to fake. There are 7 positions, and I would just write the positions above every note.
If I got lost during a song, I could just peek over and see what my fellow trombonists (tromboners?) were doing. Needless to say, band was a pretty big waste of time for me, but I got all As and Bs. Story credit: Reddit / Shazamy
