Why God Flunked Plumbing Poem by Lone Dog

I'd like to know the reason God
Designed us as He did?
His plumbing job's a total flop
And isn't worth a quid.

Our pipes routinely get clogged up
Just like a kitchen sink,
And sometimes we can get the 'runs',
Which makes our anus pink.

We often need colostomies
To give our pipes a rest,
And scopes are stuck in us to check
For polyps on request.

We gag when changing diapers and
We old folks use Depends.
We must use toilet paper which
Is rough on our rear ends.

We need to have a movement at
The awkwardest of times;
When on the road or on the phone
Or even writing rhymes.

I'd like to know the reason God
Designed us as He did?
It's caused us lots of problems from
The time that we were kids.

It's plain to see that God deserves
An 'A' when he made trees.
When they excrete, they only pass
O2 into the breeze.

The trees don't have the problem with
Their plumbing that we do.
They never worry when or where
That they might have to poo.

And trees don't need colostomies,
Nor diapers, nor Depends.
They never have to worry if
There's paper for their ends.

Now wouldn't it be nice if God
Had made us just like trees,
To only pass some oxygen
Into the morning breeze?

It seems Almighty God has played
A dirty trick on us
When He designed our plumbing so
That we would have to flush.

Just why did He, with all His smarts,
Design us as He did?
His plumbing job's a total flop
And isn't worth a quid.
