Great-granddad

I never knew my great-granddad
Nor saw what colour hair he had.
I can't be sure what job he did,
If when the rent-man came he hid.
I know that he was never rich
But not if he'd a nervous twitch,
Nor if his teeth were real or false.
I never saw him dance the waltz.

What cigarette brand did he smoke?
I wonder could he crack a joke,
Forget to button up his flies?
I think he must have liked stand pies—
A treat for all in Yorkshire life.
Perhaps he drank and beat his wife.
I must admit, to my great shame,
I can't be certain of his name.

I've only granddad's word for it
That great-granddad was such a shit.
