Yesterday’s Dilbert referenced an obscure Vulcan illness, which sent “hordes” of Dilbert fans to Google to find the reference.
In “Amok Time,” an episode that first aired on September 15, 1967, Dr. McCoy notices that the usually stoic Spock is becoming extremely irritable. Turns out that he is suffering from a chemical imbalance ? Pon Farr ? caused by a need to mate. Vulcans experience Pon Farr every seven years, and unless it is satiated, they die within eight days.
Captain Kirk redirects the Enterprise to the planet Vulcan so that Spock can marry his betrothed, a beautiful but rather forbidding Vulcan named T’Pring. But in a twist, T’Pring manipulates the situation into a fight to the death between Spock and Kirk.
