3rd Rock from the Sun is an American television sitcom created by Bonnie and Terry Turner, which originally aired from January 9, 1996, to May 22, 2001, on NBC.The show premiered three years after the film Coneheads, which was also written by the couple and featured a similar premise of extraterrestrials arriving on Earth and assimilating into American society.Dr. Mary Albright (Jane Curtin) is a professor of anthropology at fictional Pendelton State University, and many of the issues with which the four aliens struggle appear in her conversation and work.Information officer and oldest member of the crew Tommy (Joseph Gordon-Levitt) has been given the body of a teenager and is forced to enroll in high school (later college), leaving security officer Sally (Kristen Johnston) and "the one with the transmitter in his head", Harry (French Stewart), to spend their lives as 20-somethings hanging out at home and bouncing through short-term jobs.The family often communicates through Harry with their off-world (and usually unseen) boss, the Big Giant Head, who when he finally visits Earth, is played by William Shatner.Harry unexpectedly (and often in inconvenient circumstances) stands up, his arms stiff (acting as the antenna), and proclaims: "Incoming message from the Big Giant Head!"This series rerun is now also aired on Malaysia's national broadcast TV channel RTM's TV2 in the 12:30 am time slot on Tuesday and Wednesday nights.In the fall of 2011, Canada's TVTropolis cable channel began airing the show, and featured a long weekend marathon run of episodes.Primarily a source of humor, the book includes such features as "What to do if you encounter Jell-O", a fan biography of Katie Couric written by Harry, and Sally's version of a Cosmo quiz.
