Ha. There's a short story in which the narrator is invited to a dinner to eat monkey brain, but is tricked and consumed himself. Can't remember the author or name of the story (would think ea Poe or Roald Dahl). Was making a big impression on me when I first read it as a child. Anyone knows the story ?
