Yesterday's horse treat headline (see the blog posting prior to this one) reminds me of this exchange from an episode of "Futurama" in which Leela and Fry stumble upon a discovery that might explain what makes Slurm Cola so addictive:
Leela: This all must have something to do with the secret ingredient.
Fry: My G-d, what if the secret ingredient is people?
Leela: No, there's already a soda like that — Soylent Cola.
Fry: Oh. How is it?
Leela: It varies from person to person.
