4. As to the question of *why* a water bear would have an itchy back

I can only refer to this bit of (probably misquoted) verse:

Little bugs have littler bugs
Upon their backs to bite ‘em
And littler bugs have littler bugs
And on ad infinitum

[soothsayer]

5. Ha!

7. Interesting little verse.

It seems to turn up in many versions over the centuries. The oldest version I can find is from Jonathan Swift, in 1733:

So, naturalists observe, a flea

Hath 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.

[Solly Mack]

6. We all itch
