So called because it never fails to afford _funnery_. It is kept in
the buttery, is occasionally presented to persons to drink out of and
is so contrived, that by lifting it up to the mouth too hastily, the
air gets in and suddenly forces too great a quantity of the liquid, as
if thrown into the drinker's face, to his great surprise and the
delight of the standers by. _Multa cadunt inter calicem supremaque
labra._
