Star Trek is one of the most successful and well-known science fiction franchises of all time. Conceived by Gene Roddenberry in the mid-1960s, Star Trek has evolved into a massive canon including five live-action television series, eleven movies and an animated series. Star Trek is renowned for its enormous and dedicated fanbase. In 2009, the movie "Star Trek" came out using the original USS Enterprise crew and rebooting the film series using an alternate timeline.
References to Star Trek in The Big Bang Theory are frequent. All four male main characters are fluent in Klingon and often play Boggle in the language. Leonard has everyday and dress Starfleet uniforms, Sheldon has a Spock uniform, and Raj has an Uhura uniform that Priya wears. All of them can recite Spock's dying words, and Sheldon has recited dialogue of Khan Noonien Singh as well as Picard's speech about drawing the line in Star Trek: First Contact. Sheldon, a self-proclaimed honorary graduate of Starfleet Academy and Captain Kirk of theoretical physics, creates "Rock-Paper-Scissors-Lizard-Spock," and the guys always choose Spock. Sheldon has an adversarial relationship with Star Trek: The Next Generation star Wil Wheaton, who has appeared as a fictionalised version of himself on four occasions. Sheldon likes Mr. Data but Brent Spiner replaces Wheaton as his enemy.
Sheldon invites LeVar Burton, TNG's Geordi La Forge, to his home for a raffle, but he comes too late for anyone to notice him. Meanwhile, George Takei has appeared to Howard in his mind. Leonard has mentioned the Romulan Neutral Zone. The constant references to Star Trek seem to have had some influence on Penny, who was shocked when she referenced deflector shielding to Alicia in The Dead Hooker Juxtaposition. She also mentioned that her shields were up below the waist when she spent the night in Sheldon's bed in The Love Car Displacement.
