I like all the jokes that relate to the cemetary as a resort property.

Herman from time to time would tell tasteless jokes. Like, "The Elephant and the Peanut", or "The Astronaut and the Playboy Bunny".

Another one of Herman's favorites, "I just invented something to keep that thing in the car quiet, it fits right over her mouth".

The puns about them being the undead.

When Herman is reading his joke book, he says to Lily, "Wait until you hear this one, Lily, it'll kill 'ya."
Lily: "Well, it's a little late for that, but go ahead."

Lily is upset about Grandpa messing up their dealings with Event magazine. She rests her head against Herman and says, "I could just die....again."

This falls under quotes I guess but everytime I hear herman say "toot sweet" I wonder to myself what the origin of that is! That and "real wizard" are two things I've never heard of before or since the Munsters.
