Asshole Logic

Every body needs an asshole.
It is a natural fact. 
Everybody loathes an asshole,
‘Least anyone with tact.

Where would crap go without a vent?
It gives me cramps to think
Of excrement and gasses trapped
Within the colon’s kinks.

The asshole of the body shows
Intelligent design.
It’s not on top or out in front,
But down and back behind.

Yet humans, in their hubris, do
Rebel against God’s plan.
They place their assholes at the top,
And shit rains down on man.
