On the TV show The Simpsons, Patty Bouvier is Marge (Bouvier) Simpson's older sister, twin sister of Selma Bouvier. She is distinguished from Selma by her triangular earrings, circular necklace beads and pinkish dress.
Patty's only relationship with a man was a nearly one-sided fling with Principal Seymour Skinner, which she ended, giving the reason that she did not want to leave Selma. Marge told Homer: "It's Patty who chose a life of celibacy. Selma simply had celibacy thrust upon her." However, for many seasons, it was implied that Patty might be a lesbian -- when she sees Homer run through the house naked, she comments, "There goes the last lingering thread of my heterosexuality," and in a later episode she was seen coming out of the Maison Derriere burlesque house.
In February 2005, Patty came out to her sister and the world in the episode "There's Something About Marrying." When Springfield legalized gay marriage and Homer Simpson got ordained online so that he could officiate at these marriages, Patty and her golfer girlfriend planned a wedding in the chapel Homer has set up in the Simpson garage.
