How Ponies Reproduce

I believe that all ponies are gay.

But those who aren't married go cray.

So they kill all the nags,

And shove them in bags,

And grind them up with some hay.

After a pony ingests,

What used to be a pony at best,

Then the ponie gets sick

And pukes foals up real quick

And that's why ponies cannot protest.
