Quote from Lois in Lois' Sister
Hal: What? Lois: I know what I did wrong, Hal. I let her get away too easily. Hal: Well, I didn't think anything was gonna be solved once you got into who your goldfish liked better. Lois: You're right. Arguing with her accomplishes nothing. That's why I'm going to have a judge declare her mentally incompetent. Hal: That's never going to work, Lois. Lois: Are you kidding? Any psychiatrist spends five minutes with her would say that she's crazy! Hal: Lois, don't take this the wrong way, but when you two get together, you don't exactly have the high ground on crazy. Lois: Well, what am I supposed to do, Hal, just sit back and watch her die? Hal: I don't know what to do either. But Susan is an adult. You can't force someone to take a kidney. [hugs Lois]
