3rd Rock from the Sun - Season 3, Episode 27 - Eat, Drink, Dick, Mary

The Solomons wind up their third season -- and perhaps their mission on Earth -- with a romantic dinner party that turns predictably raucous. The chef is Tommy, who has just ""come out"" as a gourmet. The guests: Dick and Mary, Don and Sally and Harry and Mrs. Dubcek's amorous daughter Vicki, who is back in his life. The trouble is, Vicki's jealous ex-boyfriend is hot on her trail. He's also hot to ""put a hurt"" on the competition and kidnaps Harry just before he transmits a message from the Big Giant Head. The other Solomons miss the communique, which promises devastating consequences for the family.
