The Real Captain Of This Ship

I was waiting on you, now you’re waiting on me.

Couldn’t squeeze out one, but now I’m squeezing out three.

School always taught me the brain controls everything.

But I beg to differ when it comes to the “south wing”.

It’ll make you think, breathe, sleep, talk, and sometimes even sigh.

But only your rectum will decide when it’s time for the poop to fly.
