Having seen fishes 'fart' on at least a couple of occasions, I can't
resist - being wrapped in the past - telling the story of the day that I was
invited into a small briefing room under Whitehall.  Together with about
18-20 folks - one of whom was a Scottish, Royal Naval Captain, complete with
pipe clenched in his teeth and thumbs poking for'ard outside of his jacket
pockets.  The briefing was about sonar signatures.  (By the way.  My role
was to make coffee; hand out name badges and generally pretend that I was
half-way intelligent.)

The guy from the Scripps Insitute spoke at length about all of the various
sounds made from marine critters.  At the end of his presentation, the
afore-mentioned Captain stood to his feet and asked, in a  broad, Sean
Connery accent, "Tell me!  Do fishes fart?"  To which the answer was, in a
rich American accent, "Yes"!

Sadly we never got into the details of sound signatures.  (I wanted to
know - having seen thousands of the bastards - what a Pilot Whale's farts
sounded like?)  :-)
