What is as black as a priest, leaps like a horse, and a hundred men can’t bridle it?
The answer is in the world’s shortest poem:
Or maybe this might help –
Those who are fond of French phrases may call him pousse-pour-tous. His love of dirt and darkness suggests that he is not a person of culture, but he has his luxurious side, being also fond of warmth, cosiness and quiet situations. Though a great believer in indoor exercise, he is no fresh air fiend. His athletic powers which attracted the attention of Socrates, are very considerable. It is true he can jump into the air to a height 64 times his length, the record hovers around 200 times his length, but then he is only one-sixteenth of an inch long. As a race PI is very intelligent, and loves the circus, he lives merrily, but not long. Only five weeks at most.
So, naturalists observe, a flea
Has smaller fleas that on him prey;
And these have smaller still to bite ’em,
And so proceed ad infinitum.
Thus every poet in his kind
Is bit by him that comes behind. (Jonathon Swift)
