In The Movie, Scott dresses up like his "mom", "sister", "grandma", and "uncle" to convince Mary Lou to take him to Florida with her and Leonard.
"Grandma Leadready": Young lady, I missed my chance to go to Florida when I was the boy's age. And look at what a bitter old woman it turned me into!
Mary Lou: Oh you must be Scott's gran-
"Grandma Leadready": I CAN'T TALK TO YOU I'M TOO BITTER!
