Quote from Hal in Grandma Sues
Hal: She can't get away with this! I've had it! I'm going to toss her out on her cage. Lois: Hal, we can't do that. She's my mother. [sighs] My twisted, horrible monster of a mother. Francis: Why don't we just kill the old hag? Lois: Oh, just stop it right now. And nobody tells the boys about any of this. Hal: You mean about killing her? Lois: No, Hal. About the lawsuit.
