The 44th episode of Gene Roddenberry’s science fiction series Star Trek premieres on NBC. This early script by writer David Gerrold becomes the best-loved episode of the entire series (according to many a fan poll), introducing the rapidly-reproducing, rapidly-eating, Klingon-sniffing Tribbles to the Star Trek universe. This is their only appearance in the original series, though they reappear in the animated series and Deep Space Nine years later.
