Quote from Daphne in The Two Mrs. Cranes
Niles: That's what I love about her, her sense of humor. Cookie, darling? Daphne: Oh, no, thank you. Some of us do look after our weight. Roz: Now, now, Daphne. You have to keep your strength up. You are eating for two. Clive: You're having a baby?! Well, when you were planning on springing that news? Daphne: We don't like to bring that up. It's a sore point around here, what with my sister-in-law being barren and all. Niles: Now, now, it's not her fault. You see, my brother is impotent.
