Tiffany was one of Peter Griffin's Mormon wives in "The Father, the Son, and the Holy Fonz", along with Nancy the Postal Lady and Kimmy. She yelled at traffic for a living, and looked homeless. When she first met Peter, he was trying to find his religion, and he decided to first experiment in Mormonism. After being informed that he can't drink alcoholic beverages as a Mormon, he kills all three of the Mormon wives.
