The Flintstones: Season 4, Episode 10

4 - 10: Sleep On, Sweet Fred

Betty and Wilma learn from a talk show that if they whisper to their husbands while they are sleeping, they can work their will on them with the boys never suspecting a thing. The trick works like a charm on both Barney and Fred, who now accompany their wives uncomplainingly on trips shopping and to the beauty salon, among other things. Then Fred, while awake, overhears the girls talking about what they've been up to, and he comes up with the perfect way both to get even with the girls and to nip in the bud their latest effort: to get the boys to buy them mink coats.
