Learning Math on TV

Nobody seems to have an answer to the question, "What TV show did John Edwards' father learn math from?" Considering Edwards' age, this must have been somewhere between 1955-1962, several years before Sesame Street. Gumbi? Mr. Ed? How about some Howdy Doody reruns?

Let's see...
Learning Math on TV
Christmas in Cambodia
Boston Marathon
M16/Chinese Assault Rifle
Enemy Fire
"I've been consistent on the war since the beginning."
etc.

How many on-the-spot lies does that make for the Johns? I'm losing count.
