Today, exactly 50 years ago, "Amok Time" the 5th episode of the second season of Star Trek, the original series (TOS) aired in the United States. In this episode Spock suffers from pon farr, a Vulcan mating urge. He dies when he does not return to Vulcan to marry his fiancé. The Enterprise traves to Vulcan, of course, to save Spock.
Remarkable about this episode is the German version which aired in January 1974 on ZDF, the "Zweites Deutsches Fernsehen" (second german television channel). ZDF cut several scenes, changed the ordering and altered the dialog to avoid anything sexual. Spock just suffers from "Weltraumfieber" (space fever), as the epsiode was called.
And Amok Time is the epsiode where Leonard Nimoy invents the famous vulcan greeting.
Live long and prosper
