Sherry: Coffee's on. Want a cuppa?
Frasier: No thank you, caffeine only weakens the immune system. I'm fighting off a flu.
Sherry: Oh, I'm sorry. Let me get you some breakfast.
Frasier: No, no, That's really not necessary.
Sherry: Oh, no, no. You'll feel much better once you've had my scrambled-egg tacos and Spam patties.
Frasier: In keeping with the trusty adage, "starve a cold, disgust a fever."
