Star Trek

Being science fiction nerds, Sheldon, Leonard, Raj and Howard are all Star Trek fans. Both Leonard and Sheldon agree that the Original Series is better than the Next Generation, but that Picard is better than Kirk. There have been references made to TOS, TNG, DS9, and the newest spinoff, but not to Voyager or Enterprise. Sheldon believes that Star Trek: The Motion picture was the worst movie and The Voyage Home was the best, while Raj thinks that The Final Frontier was the worst and The Wrath of Khan was the best. All main characters can speak Klingon and quote Star Trek movies often.
