C, E-flat, and G go into a bar. The bartender says, “Sorry, but we don’t
serve minors.” So E-flat leaves, and C and G have an open fifth between
them. After a few drinks, the fifth is diminished, and G is out flat. F
comes in and tries to augment the situation, but is not sharp enough. D
comes in and heads for the bathroom, saying, “Excuse me; I’ll just be a
second.” Then A comes in, but the bartender is not convinced that this
relative of C is not a minor. Then the bartender notices B-flat hiding at
the end of the bar and says, “Get out! You’re the seventh minor I’ve found
in this bar tonight.” E-flat comes back the next night in a three-piece suit
with nicely shined shoes. The bartender says, “You’re looking sharp tonight.
Come on in, this could be a major development.” Sure enough, E-flat soon
takes off his suit and everything else, and is au natural. Eventually C
sobers up and realizes in horror that he’s under a rest. C is brought to
trial, found guilty of contributing to the diminution of a minor, and is
sentenced to 10 years of D.S. without Coda at an upscale correctional
facility.
It’s still much too early in the day for me to handle that many groans per minute. 
Scusa, the puns runneth over.
I enjoyed that. Thank you.
In a similar (but less convoluted and non-musical) vein, anyone know the frayed knot joke?
(Please just Google it if you don’t so I don’t have to tell it here!)
I’m afraid not…never heard that one before !!
Heard it before, but still punishment of the highest odor.
It might as well have been an Iron bar. Ouch. The late great Tommy Cooper had a hundred one-liners like that.
Nice one, O! More music theory than I can handle in one lump, though…
