"Wormhole X-Treme!" is the 100th episode of military science fiction adventure television show Stargate SG-1 and is the 12th episode of the fifth season. The episode was first broadcast September 8, 2001 on Showtime in the United States. It was written by series co-creator and executive producer Brad Wright along with supervising producers Joseph Mallozzi and Paul Mullie and was directed by Peter DeLuise. In the episode, Stargate Command learns that an alien ship belonging to the same race as Martin Lloyd is heading for Earth. They locate Martin, who having once again lost his memories has created a television series called Wormhole X-Treme!, seemingly based upon the top secret Stargate Program. The story centres around a show-within-a-show called Wormhole X-Treme! which parodies Stargate SG-1. In creating the episode, Wright and all those involved sought to create a comedic episode that celebrated the show through parody, cameo appearances, inside and metafictional jokes and references. The episode is a sequel to "Point of No Return" from the shows fourth season. The season ten episode "200" follows up on characters and events from the episode. Plot An alien space ship has been detected heading towards Earth, and based upon it's energy signature Major Samantha Carter (Amanda Tapping) believes that it belongs to the same race of people as Martin Lloyd, who Stargate Command set about locating. They find Martin, who has become the creative consultant on a science fiction television show he sold called Wormhole X-Treme!, which bears striking resemblance to the real life top secret Stargate Program. Under the guise of being the shows Air Force consultant, Colonel Jack O'Neill (Richard Dean Anderson) is sent to the studio where Martin is working on the show in order to learn what he can from him about the inbound ship. O'Neill reintroduces himself to Martin (Willie Garson), who despite having previously met, claims not to remember him. Believing that Martin has once again had his memory erased, O'Neill searches his trailer and uncovers numerous vitamins, which he relays back to General Hammond (Don S. Davis) at Stargate Command, who dispatches the rest of SG-1 to assist. Soon Dr. Fraiser (Teryl Rothery) determines that the vitamins found contain the chemical used by Tanner, another member of Martin's race who was previously responsible for drugging him. Meanwhile, Carter and Dr. Daniel Jackson (Michael Shanks) establish that, also like last time, surveillance devices have been setup
