Quote from Niles in Daphne's Room
Martin: I still think you're making too big a deal out of this. Niles: Dad, I have never seen Maris this angry. I swear, her eye was twitching like a frog in a science experiment. Martin: Well, when your mother got mad at me, I'd just grab her, bend her backwards, and give her a kiss which made her glad she was a woman. Niles: I can't do that with Maris. She has abnormally rigid vertebrae, she'd snap like a twig.
