Stony Curtis: Nice place you have here, Mrs. Flintstone.
Wilma: Oh, my, nothing really.
Wilma: Oh, would you care for some hors d'oeuvres? (rings a bell) Oh, Yvette!
Fred: Yvette? Who's Yvette?
(Betty appears dressed as a maid and using a French accent)
Betty: Oui, Madame. You called?
Wilma: Yes. Will you please serve the hors d'oeuvres?
Betty: Oui, Madame.
Fred: What's going on here? That's not Yvette, that's Betty.
Wilma: You're confused, Frederick. Betty is the upstairs maid.
Fred: Upstairs maid? We don't have an upstairs maid! WE DON'T EVEN HAVE AN UPSTAIRS!
