Quote from Niles in The Unnatural
Frasier: Oh, I can live with playing badly in front of my co-workers. It's Frederick I'm worried about. He's still at that age where he thinks his father can do anything. Niles: Every child at some point must discover that his father is not a superhero. Frasier: I know. Niles: It's a healthy part of the developmental process. Frasier: I know, I know. Some day he's going to have to learn that I'm not perfect. It's just I was hoping it might be something less humiliating, like seeing me fast-dance at a family wedding. Niles: You consider that less humiliating?
