Anyway, here it goes:

The Vermin only teaze and pinch Their Foes superior by an Inch. So Nat'ralists observe, a Flea Hath smaller Fleas that on him prey, And these have smaller Fleas to bite 'em, And so proceed ad infinitum.

Great fleas have little fleas
upon their backs to bite 'em,
And little fleas have lesser fleas,
and so ad infinitum.
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.

Big whorls have little whorls,
Which feed on their velocity,
And little whorls have lesser whorls,
And so on to viscosity.

Big bubbles have little bubbles
which feed on their liquidity
and little bubbles have lesser bubbles
and so on to volatility.
And the greater bubbles have themselves
even greater bubbles to ride on;
while these again have greater still
and greater still, 'till meltdown.
