Malcolm: So, yesterday, in my gifted class - I'm not bragging that I'm gifted, but that's just what they call the class. We're studying Bovine Spongiform Encephalitis, it's a Mad Cow disease. It started because they were grinding up dead cows to feed them to the other cows. Basically the prions turn their brains into soup, right in their skulls. It's very similar to a disease that afflicted a tribe of cannibals, because they feasted on their victims' brains. [Patty is silent]
