S6E7 The Great Gazoo

Fred and Barney stumble upon a two-foot-tall green alien named Gazoo, who quickly takes on the role of their servant. When they decide to enjoy a fancy dinner out, believing Gazoo will foot the bill, things take a turn for the worse when the alien vanishes. Left high and dry, the Flintstones and the Rubbles find themselves stuck washing dishes to cover the cost of their meal.
