Fleas and Mathematics

In the popular-mathematics book I'm reading, there are a number of little poems and quotes. You may have heard the following before. Quotations are courtesy the Wikipedia.

"So nat'ralists observe, a flea
Hath smaller fleas that on him prey,
And these have smaller fleas that bite 'em,
And so proceed ad infinitum."
-- Johnathan Swift

"And the great fleas themselves, in turn,
have greater fleas to go on,
While these again have greater still,
and greater still, and so on."
-- Augustus de Morgan
