Quote from Haley in Good Grief
Haley: You know, there's a deep psycho-spiritual connection between sex and death. Look at Freud. Thanatos, Eros... locked in an eternal struggle. Alex: How do you know any of those words? Haley: I don't know. Maybe I remembered something from school somehow. They say everything you've ever heard is locked in your brain somewhere. Another fun fact... your brain burns 20% of the calories you consume. [microwave beeps] My burrito! Alex: Another one? Oh, my God. I think your brain is finally working because, for the first time ever, you're not starving yourself. Haley: That is a credible hypothesis.
