Both Wally (Tony Dow) and Eddie (Ken Osmond) are up for a job at the local ice cream emporium, but it's Wally who lands the position. He also wins the adoring attention of the pretty girls who frequent the establishment, making Eddie mighty jealous. Hoping to get even, Eddie and Lumpy (Frank Bank) cook up a scheme whereby Wally will deliver six quarts of ice cream to the home of Mary Ellen Rogers (Pamela Baird) during a girls-only slumber party -- thereby incurring the wrath of Mary Ellen's father. In the episode's uproarious climax, Wally concludes that revenge is a dish best served cold (as cold as ice cream). ~ Hal Erickson, Rovi
