While shopping for some cans
An old man passed away
He floated up toward Heaven
But got lost along the way
Now he's the love-matic Grandpa
The wise Socratic Grandpa
He'll fill our hearts with looooooove

the name
He took it from a boxer named Johnny Paycheck. He figured everybody could relate to having (or Needing) a paycheck.

Or is it Frere-Jones? Does it matter?

might be nit-picking…
But maybe not, considering this is a 52-part series…
