Lady Bouvier's Lover - Plot

Plot

The whole Simpson family gathers to celebrate Maggie's first birthday. At the party, Grampa feels lonely and bored, so Marge suggests she set him up for a date with her mother, Jacqueline Bouvier. Eventually, the elderly couple falls in love, which upsets Homer; his theory is that if the pair married, he and Marge would be brother and sister and the children would look like freaks (Homer's vision of the children as freaks depicts them as realistic children, in contrast to the cartoonish portrayal of humans in the series, and his description of a freak is a person with normal coloured skin, no overbite and five fingers on each hand). To impress Marge's mother, Grampa takes her out on the town, but when he does, Mr. Burns steals her from him. Grampa is heartbroken. Mr. Burns declares that he is in love with Mrs. Bouvier, and they are going to get married, against Marge's interests. Meanwhile, Bart buys a $350 Itchy & Scratchy animation cel with one of Homer's credit cards. In order to pay Homer back, Bart blackmails Mr. Burns for $350.

On the day of the wedding, Mr. Burns and Marge's mother attempt to marry. However, Grampa crashes the ceremony and asks that Mrs. Bouvier marry him instead of Mr. Burns. Partly due to Mr. Burns's obnoxious behavior, she declares that she does not want to marry either man, which is good enough for Grampa. He grabs her and they hop on a bus.
