I happen to have read an article about kuru several years ago, so I was able to shoot back (or, more honestly, stutter back) “Um, the disease brain-eaters get, right? Human brains? With the, the, the prions?” (I am less than eloquent on the spot, but all the key points are there, my friends.)
But who, having read this once in her life, wouldn’t remember it? Brain-eating cannibals, people.
