Lady Bouvier's Lover (S05E21)
The Simpson family gathers to celebrate Maggie's birthday. After the party, Grampa feels depressed, so Marge sets him up for a date with her mother, Jacqueline. Eventually, the couple falls in love, which enrages Homer.
To impress Jacqueline, Grampa takes her out dancing, but when he does, Mr. Burns steals her from him and breaks his heart. Mr. Burns declares that he is in love with Jacqueline, and they are going to get married, against Marge's interest. 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 by threatening to ruin his suit before his date.
On the day of the wedding, Mr. Burns and Jacqueline attempt to marry. However, Grampa crashes the ceremony and asks that Jacqueline marry him instead. Partly due to Mr. Burns' boorish behavior, she decides not to marry either man. Deciding that Jacqueline decision is good enough for him, Grampa grabs her and they run out of the church and onto on a bus.
