There was a TV show (in the black and white era) called “Leave it to Beaver”. Beaver is the nickname of the younger son, his brother is Wally, mother June, and father Ward, I think. Their last name is Cleaver.

It was a “wholesome” sit-com where the kids would get themselves into some situation, then try to hide it, then would be found out, then it would be resolved.

(I didn’t watch it extensively, sorry if I’ve over simplified and annoyed any fans.)

If you’ve ever seen the movie Pleasantville, the black and white portion is basically Leave it to Beaver.

My favorite reference to it comes from the movie Airplane, wherein the woman that plays June happens to be fluent in Jive, playing against her suburban housewife type. It’s hilarious. “Excuse me, stewardess. I speak Jive.”
