I give you now Professor Twist,
A conscientious scientist.
Trustees exclaim, 'He never bungles!'
And send him off to distant jungles.
Camped on a tropic riverside,
One day he missed his loving bride.
She had, the guide informed him later,
Been eaten by an alligator.
Professor Twist could not but smile.
'You mean,' he said, 'a crocodile.'
-- Ogden Nash
