The Purist
by Ogden Nash
I give you now Professor Twist,
A conscientious scientist,
Trustees exclaimed, "He never bungles!"
And sent 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."
I’m a professor but at times do opt for the wrong word, and can appreciate people who are annoyed by pedants, so this was doubly appreciated.
Thanks.
