Joke

Not sure where this originated; a neighbor posted it at an on-line community:

C, E^b, and G go into a bar. The bartender says, “Sorry, but we don't serve minors.” So E^b leaves, and C and G have an open fifth between them. After a few drinks, the fifth is diminished, and G is out flat.

It goes on from there, although I wonder if there are not (ahem) diminishing returns.
