Season 5

The Solomons are relieved when Vicki's baby turns out to be human, but horrified when she announces her plans to sell her story to the papers. When a reporter comes sniffing around, Sally gives Dick the title of Security Officer and orders him to kill him; however he can't, so she makes him High Commander and herself Security Officer so that she can kill the reporter herself. Dick then reminds Sally that he is now the High Commander, and that there is nothing she can do to reverse it.

When a drunk Mary tells Dick she once had a fling with his archenemy Vincent Strudwick, he is outraged and decides to get even with the pair of them by convincing Strudwick's wife to sleep with him. Tommy supports Dick's decision, imagining double dates - himself with Alissa and Dick with Strudwick's wife. Meanwhile, Sally gets the hots for Don after he starts riding a police motorbike, but the pair crash and Don ends up in full body plaster.

Dick crashes the car into a tree and calls an insurance company to cover it, but the salesman informs him that in order to be covered, he needed to have taken out insurance before the crash. Instead, the salesman manages to convince Harry to buy insurance, but then ignores all of Harry's attempts to call him. Dick, meanwhile, is pleasantly surprised when he discovers just how much more advanced his rental car is than the old Rambler, and so sells the latter for scrap; however, the Solomons soon begin to miss it.

When Mary and Nina talk about how good looking Harrison Ford is, Dick decides that he himself is hideous and visits a plastic surgeon to discuss having his face surgically altered. However, when the surgeon tells Sally that she might benefit from having some plastic surgery herself, she becomes paranoid and believes herself not to be good enough for Don. Harry, meanwhile, is chuffed when the surgeon tells him that his face is perfect.

Dick is confused when Nina won't let him accompany her to her Black Student Union meeting, believing it to be a Weight Watchers type club; so, in an attempt to understand the concept, he mistakenly takes the Solomons to a racist white power rally. Dick realizes that the rally was a bad idea, and tries to make it up to Nina by firing her, to release her from what he calls her 'servile role' (as he and Mary's assistant), but she informs him that she is happy in her job. Meanwhile, Sally, Harry and Tommy are preparing to take part in a poetry competition and decide to use racism as their subject.

Mary is horrified when she learns that Dick has been pocketing all the tip money she has left at restaurants, but Dick is baffled by the concept of tipping, and attempts to re-invent it by placing a stack of one dollar bills on the table and informing the waitress that when she pleases him, the pile will grow, and when not, it will shrink. Mary, however, informs him that this idea is demeaning. Meanwhile, Sally goes on the pill after Tommy informs her that she could become pregnant by having sex with Don, but begins to experience erratic mood swings and food cravings.

At a charity auction for the Rutherford Boys Home, Dick wants everybody to applaud him and so starts a bidding war with Studwick for a painting and ends up paying seventeen hundred dollars for it.

Back at home, Harry and Tommy have been given the job of devising a new mission statement, and so try to work out what their purpose is on Earth.

Mary reveals to Dick that she has been observing his family for a number of years and that she would like to make a documentary about them, in order to show how the 'typical American family' has changed.

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.

Valentines Day is approaching and Tommy hopes to get a hotel room and lose his virginity to Alissa, however, he is nervous when he discovers that she is sexually experienced and so loses his virginity to Mary's niece Tiffany first. Meanwhile, Dick discovers that Mary is seeing a therapist and, paranoid, he starts seeing her too, in order to find out what Mary has been saying about him.
