I can't tell if any fleas
Have smaller fleas upon them;
But I can feel that on these fleas
Are giant jaws; and toothsome.

These fleas are opportunists, sure,
They hop from leg, to arm, to floor;
Each leaves behind a bit of gore:
There's nothing smaller I abhor.

They're nearly invisible and yet
Upon me I can feel them set;
And tear out great big chunks of- Nyet!
A bigger fiend, I've never met.
