Urologist Flat World Logic

Hello! Is there a world or universe out there? Is it flat a scary?

Urologist Flat World Logic

According to our urologist the world is flat
The bladder is full, roundish and soft
Peas are green.  Pee is yellow
He is a happy fellow small and plump
Hails from a land more advanced than us
Where things fall off all of a sudden
Before the pub but after the postal stop
Gone too soon for their own good

Oblivion, urology is all the same stuff 
One man's nothing is another man's logic
There are no countries called Urine-Nation
No planets called Urine-Trouble
But there could be an infection down under

What is that thing floating around the sun?
Doctors say it is a figment of your imagination
Our Urologist will say anything for a dollar
He will swear the Earth is a pancake or Truffle
Or a cosmic muffin if paid enough
