Granddad..?

You can think till your brain hurts,
You can ponder till you're fit to drop.
But the fore engined, wizz bang question,
Dose a Chiropodist chirop?

I laughed to my Granddad and he laughed to me,
And we both laughed together a lot.
You can't ask him that said my Grandma,
Does a Chiropodist chirop?

How do we find out? I asked Granddad,
Well we have to work with what we've got.
A Cleaner cleans and a Dancer dances so,
Does a Chiropodist chirop?

That's true I told Granddad,
But a Doctor will never doct.
Well if you know it all Toby why don't you tell me,
Does a Chiropodist chirop?

I don't know it all Granddad, that's why I ask you,
For your knowledge exceeds to the top.
And yet even you cannot answer the question,
Does a Chiropodist chirop?
