No, not that weird comic strip starring the two naked people. It's a children's religious pamphlet from 1971 that demonstrates how you should and shouldn't act a la "Goofus and Gallant" of Highlights Magazine. Or to quote the Simpson's, "Don't do what Donny Don't Does."
I think I might have to side with our little whiner here. He and Ron appear to be about the same age, they even look alike -- maybe twins. Clearly Mom and Dad are playing favorites. Even the dog recognizes that.
The writers of this pamphlet have clearly never been married.
