Quote from Frasier in The Show Where Lilith Comes Back
Daphne: Oh, my head! Frasier: Can I get you an aspirin, Daphne? Daphne: Oh, no, no, I'm afraid those are useless. This is one of me psychic headaches. There's some kind of negative force out there. I only get these when there's a clawing at the cosmic continuum. Niles: Perhaps if someone rubbed your temples? Frasier: Niles! I'm sure she wants privacy while she contacts the mother ship.
