There was a fellow who did the college cicuit back in
the 70's- he wrote a song called "Eddie Haskell" and
one of the lines was "good evening Mrs. Clevage- How's
the Beaver?"
He also had a song about getting a vasectomy,
and a line in the chorus was "All the juice, no seeds!"
And what about that Norah Jones tune ("Don't know why I
didn't come!")
