Superman had a grandfather.

Nobody knew his name,
but they knew of him.
He was Krypton’s Chief Farmacist,
collecting wheat for the masses.

He would often call from the fields,
“Kal-El, Kal-El!”

And Kal-El would come.

“We shan’t speak further,
for nobody knows what ‘shan’t’ means anymore.
That, and we could be blown to bits…
for copyright infringement.”
