Droppings, droppings, o'er the world,
some are straight and some are curled.
Some are black and others brown,
droppings, droppings, all around.
This poem is (about) dog shit.
Edit: Thank you, Radrook, my friend! You're right, the last line sounds better with "all around." Then again, not sure if that's a good thing, since the poem is intentionally bad, but hey, I think that's clear enough on its own.
