"My Sphincter Cannon" By Alexander The Poet 

When I need to take a shit,
Going to the bathroom is never fun,
The toilet I do defeat,
With the power of my, sphincter cannon!

A Sphincter is a muscle,
That controls the output of the feces
It makes crapping possible,
That's one of it's responsibilities

My sphincter is sensitive,
And eating the wrong food may just create
An outburst so destructive,
That it is guaranteed, to devastate!

If you see me eat tacos,
Here's a warning, you better start to run
Whether you're a friend or foe, 
You'll feel the wrath, of my sphincter cannon!

THE END
