Herman Munster: Oh, goody!
Lily: Eddie! You better start dawdling, or you're going to be on time for school!
Lily Munster: Herman tried to build a ship inside a bottle. We had to break the bottle to get him out.
Lily Munster: Grandpa, if you want the ketchup, just say "Please pass the ketchup", not "Shoot me the plasma!"
Lily Munster: When is that silly bird going to get girls off his mind?
The Raven: Nevermore, nevermore.

Herman Munster: DARN, DARN, DARN, DARN!
Lily Munster: Oh, Marilyn... the circles under your eyes. How lovely you look today.
Marilyn Munster: What does Ramone look like?
Lily Munster: He looks a little like Cary Grant, the poor man.
Herman Munster: [reading a poem he wrote as an advertising jingle for his mortuary employer] When your days on earth are over / And you've gone to your reward, / Let us put you 'neath the clover / At a price you can afford.
Grandpa Munster: Hmm. What smells so good?
Herman Munster: I cut myself shaving.
