A Token Fly Poem

All poets have to write one day A poem about a fly they knew; And there's no escaping it, So with no more adieu I introduce the fly, one night Who bit my leg till I saw daylight: He bit deep and he bit long, My vital fluids began to seep. He bit a bite for every fly Who at the hand of man, must die; He bit a bite for every woe And curse on flies, by human foe; He put his species pain on me Without so much as a thank you; please, And without a word, I squashed his guts And stomped his itty, bitty nuts; If he had some, they're surely flat; If he didn't- that's the end of that.
