Oops

In the Cathedral of Girgenti, in Sicily, the slightest whisper is borne with perfect distinctness from the great western door to the cornice behind the high altar, — a distance of two hundred and fifty feet. By a most unlucky coincidence, the precise focus of divergence at the former station was chosen for the place of the confessional. Secrets never intended for the public ear thus became known, to the dismay of the confessors, and the scandal of the people, by the resort of the curious to the opposite point, (which seems to have been discovered accidentally,) till at length, one listener having had his curiosity somewhat over-gratified by hearing his wife’s avowal of her own infidelity, this tell-tale peculiarity became generally known, and the confessional was removed.

Miniatures

In 1925 New York poet Eli Siegel composed the shortest poem in the English language. He called it “One Question”:

I.
Why?

The former record holder was an anonymous verse titled “On the Condition of the United States After Several Years of Prohibition”:

Wet
Yet.

Relative Logic

You say that you have a dog.

Yes, and a villain of a one, said Ctesippus.

And he has puppies?

Yes, and they are very like himself.

And the dog is the father of them?

Yes, he said, I certainly saw him and the mother of the puppies come together.

And is he not yours?

To be sure he is.

Then he is a father, and he is yours; ergo he is your father, and the puppies are your brothers.

Let me ask you one little question more, said Dionysodorus, quickly interposing, in order that Ctesippus might not get in his word: You beat this dog?

Ctesippus said, laughing: Indeed I do; and I only wish that I could beat you instead of him.

Then you beat your father, he said.

— Plato, Euthydemus
