3rd Rock from the Sun
The premise of the show revolves around an extraterrestrial research expedition attempting to live as a normal human family in the fictional city of Wrutherford, Ohio, said to be 52 mi (84 km) outside of Cleveland, where they live in an attic apartment. Humor was principally derived from the aliens' attempts to study human society and, because of their living as humans themselves while on Earth, to understand the human condition. This show reflects human life from the perspective of aliens and many sources of humor are from the learning experiences the alien characters have. Most of the episodes are named after the protagonist "Dick". In later episodes, they are more accustomed to Earth and often are more interested in their human lives than in their mission.
The show also takes humor from its mirroring of all human anthropological expeditions and their assumptions of superiority to the "natives", as well as their inability to distinguish themselves from the natives. 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. Furthermore, these four alien researchers end up looking more or less like joyriders as they get drawn further and further into human life.
Dick Solomon (John Lithgow), the High Commander and leader of the expedition, is the family provider as a physics professor at Pendelton (with Ian Lithgow, John Lithgow's eldest son, playing one of his less successful students). 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 show also involves their relationships with humans, mostly their love interests.
The family often communicates through Harry with their off-world (and usually unseen) boss, the Big Giant Head, who when he finally visits Earth, appears in the body of 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."
