Why This Is Hell

I'd rather not. I came across this sort of thing on a Blue Peter annual in the early-1970s, with a picture of - now then - Peter, John, Val and Lesley holding up a cover of Peter, John, Val and Lesley holding up.... I didn't hold with it then.

A (not so) Swift ditty:

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.
