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.
Profesor Twist could not but smile.
“You mean,” he said, “a crocodile.”
