In this (joke) laxative ad featuring the Flintstones, Fred Flintstone and Barney Rubble are hanging out together in the Flintstones' living room; then Fred goes into the bathroom, shuts the door, and from the living room we hear: "Yee-ow!" Then Fred walks out of the bathroom and says: "Barney, my poop is petrified!" to which Barney says: "What's it afraid of, Fred?" and laughs. "Very funny!" says Fred, who continues: "No, Barney, I mean my feces is fossilized!" Then Barney asks: "Did you lay a dinosaur egg?" and Fred answers: "It felt like one: a brontosaurus!" Then Wilma walks in and says: "What are you two talking about?" And Barney tells her Fred is constipated, and she tells Fred to take (whatever brand of laxative).
Then the slogan is: "(Laxative brand): the stone-age solution to stiff-as-stone stools."
