Doctor Dan, the butt man
 

Ode to the Proctocologist.

Doctor Dan finished at the top of his class.
Now he cradles your nuts while he looks up ass.
He gets two opinions on your prostrate exam
One with his winky and the other with his hand.

He tells everybody that he's a brain surgeon
But he buys KY jelly and gloves by the dozen.
Truly he's a master of colons and sphincters
and people hardly notice that he sniffs his fingers.

yuck.

surgeon and dozen don't rhyme.

No, no it doesnt
