The Flintstones: Season 2, Episode 18

2 - 18: The Entertainer

To please his boss (and possibly be promoted), Fred agrees to entertain a woman named Greta Gravel (voiced by Paula Winslowe) by taking her out for a few nights. But nothing goes easily in Fred's world, and Greta runs into Wilma, who shows up at the same restaurant with Barney and Betty. As Fred's bad luck would have it, Wilma and Greta were high school classmates. Fred can't be seen out with another woman (especially by his wife!), nor can he abandon his boss' business client.
