Those lyrics, which you've probably never heard (with good reason), are below, and I'm convinced that Hefti had another comic book pair in mind at the time he wrote them. For the record, I'm okay with the "youthful ward" thing; poor boy and rich man, helping each other out. It's okay, it's the way of the world.
But ... "boy pals"? No. No, that's just wrong...
No matter where they go
They are known as the couple.
They're never seen alone
So they're known as the couple.
As I've indicated
They are peas in a pod.
Don't you think that it's odd.
Their habits, I confess
None can guess with the couple.
But they're laugh-provoking;
Yet they really don't know they're joking.
