Gwen, Larry, Dick & Mary - S5.E10

Mary is tired of spending all of her time with Dick's family and so suggests that the pair befriend another couple - her tennis partner Gwen and her husband Larry. Dick is apprehensive but quickly warms to the pair; however, they soon start brushing he and Mary off, so Dick finds them at the tennis club, where they tell him that it's because they find Mary to be tedious and self-absorbed. Meanwhile, Sally, Harry and Tommy are forced to use the laundromat when their washing machine breaks down, and immediately fall in love with the place, even setting up a laundromat court, in which Sally, imitating several of the phrases and mannerisms of Judge Judy, settles squabbles over people's washing.
