The meaning of a phrase

What is the meaning of the phrase "It takes a village to raise an idiot?"

I think it's just a goof on Hillary Clinton's "It Takes a Village [To Raise a Child]". That is, it has no meaning; it's just a joke.

I think Hilary stole an old African saying. Yes, it's poking fun at this, and is helped by the fact that the concept of "village idiot" is well-known.
