Music joke

[kiralademaus]

For those of my friends who are musically inclined and know at least a little about theory...

A Bb, a Db, and an F walk into a bar. The bartender takes a look at them and says, "Sorry, we don't serve minors."

So the Db leaves and the Bb and the F have an open fifth between them. *ba-dum-dum-KSSSHHH!*
