Quote from Frasier in The Improbable Dream (Part 2)
Frasier: Excuse me while I was blinking, did we all just suddenly time travel back to the age of the druids? Lilith: I'm not saying the dream was psychic. But perhaps your subconscious mind has observed something subtle between Rebecca and Robin Colcord that disturbs you. Carla: Well, I know how to find out right now. Sammy, give me some of your fingernail clippings. I'll have Madame Mazora burn them and inhale them while she's in a trance. Frasier: Oh, take Lilith along. The three of you can gather round the kettle and stir.
