What’s in an asshole?

It is but a hole beneath one’s ass
Probe it if ye will, but heaven knows I shall pass
For it pains me to try and fathom
what lies deep inside one’s bottom
Seeing, ye say, is believing?
Rest ye assured, I am content just from assuming

What, still ye ask, is in an asshole?
Did ye not heed my words in whole?
If ye insist to know it all,
then allow me to be literal
What ye shall find in that narrow pit
is but feces, crap, poop, and shit

Vulgar, ye say, is my word?
I only but say what ye want heard
I told ye the fact was obvious,
but still ye seem to be curious
Now say ye believe me not?
Rest ye assured, I shit ye not
