"Foxy Grandma" is the twenty-first episode of the third season and the eighty-first overall episode of the original series, The Flintstones. It first aired on February 8, 1963.


Fred tries to find a maid so that Wilma doesn't have to do household chores. This turns out to be easier said than done.


Grandma Dynamite, a TNT-stick-throwing, masked, sexagenarian bank robber, and her burly grandson-accomplice, Sonny, have plundered the First, Second, and Third National Banks and require a place to craftily hide themselves while police are cordoning and probing Bedrock for them. They are in a park, ruminating about this situation, when they overhear fellow park-visitors Fred and Barney's talk about Fred needing a competent housekeeper while Wilma is pregnant.

All of the Bedrock Employment Agency's housekeepers have proven unsuitable in service to the Flintstones (Peaches was a glutton who selfishly depletes Fred's icebox food supply; Bubbles was too tightly self-scheduled, and Fred and Wilma were not permitted the time that they require to eat Bubbles' cooking), and Wilma will summon the aid of her mother, whom Fred detests, unless Fred can find acceptable housewife's help. Grandma Dynamite decides to pose as Flintstone housekeeper "Dinah" and, in the park, approaches and effortlessly convinces Fred to hire her.

"Dinah" uses her supply of dynamite to explosively open the stubborn door of the Flintstone icebox, and Wilma questions the sanity of "Dinah" and Fred's judgement in housekeeper selection. "Dinah" and Sonny have planned an excursion to downtown Bedrock to obtain some items, including "lettuce", but Sonny's driver's licence is suspended, and Fred offers to transport "Dinah" and her grandson to what he thinks will be the Bedrock Market. However, "Dinah" and Sonny direct Fred to the parking space outside of the Fourth National Bank, where Grandma Dynamite "strikes again", and Fred discovers that his is the getaway vehicle for the notorious criminals, with him as their hostage.

The three return to the home of Flintstone, where Wilma's mother, Pearl Slaghoople contacted and invited by Wilma to house-keep after Wilma observed "Dinah"'s bizarre behavior with the icebox door dynamite blast, single-handedly "throw(s) out the trash" (i.e. the explosive elderly larcenist and her kin), but her suitcase is identical to and is confused with that of Grandma Dynamite, and when the police quest for the still-at-large Grandma Dynamite extends to Fred's house, two dedicated constables witness mother-in-law opening what she thinks is her suitcase and finding the bank robbery booty inside. They promptly arrest her, much to Fred's amusement!
