    • Ralph: What's Lyme Disease?
      Principal Skinner: I'll field that one. Lyme disease is spread by small parasites called ticks. When a diseased tick attaches itself to you, it begins sucking your blood. Malignant spirochetes infect your bloodstream, eventually spreading to your spinal fluid and on into the brain.
      Miss Hoover: The Brain? Oh dear god!
