‘Sumps and rigor

Assumps and rigor, ‘sumps and rigor
Go together with utmost vigor.
This I tell you brother
You can’t have one without the other.

Assumps and rigor, ‘sumps and rigor
It’s an institute you can’t figger.
Ask the local gentry
And they will say it’s elementary.

Try, try, try to separate them
It’s an illusion.
Try, try, try and you will only come
To this conclusion.

Assumps and rigor, ‘sumps and rigor
Go together with utmost vigor.
We were told so leery
You can’t have one, you can’t have none,
You can’t have one without the theory.

Assumptions, ‘sumps and rigor
Try, try, try to separate them
It’s an illusion.
Try, try, try and you will only come
To this conclusion . . .
