[Thatcherite]

From memory, so possibly slightly innaccurate:

The turtle lives tween plated decks
Which practically conceal its sex
It puzzles me how the turtle
In such a fix can be so furtle

[Liberal Classic]

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."
