Caution: Music Joke Ahead

So, three notes walk into a bar -- a G, an Eb, and a C.
The bartender looks up and says "We don't serve minors."
So the Eb leaves and the other two have a fifth between them.
After a few drinks, the G was out flat, and the experience was diminished.

Eventually, the C sobers up, sees one of his friends missing, the other one passed out, and realizes to his horror that he's under a rest.

C was brought to trial, found guilty and convicted of contributing to the diminution of a minor and was sentenced to 10 years of D.S. without Coda at the Paul Williams/Neil Sedaka Correctional Facility.
