Quote from Emily in The Third Lorelai
Trix: Good, that means the majority of your blood is Gilmore blood. Gilmores don't get sick. Am I right? Richard: We wouldn't dare, Trix. Trix: That's right. Your mother is always sick. Emily: I am hardly always sick. Trix: You're sick right now. Lorelai: Are you sick now, Mom? Emily: Headache. Trix: Gilmore's don't have headaches. Our heads are perfect.
