Perfect Strangers is an American sitcom that ran for eight seasons, from March 25, 1986, to August 6, 1993, on the ABC television network. Created by Dale McRaven, the series chronicles the rocky coexistence of midwestern American Larry Appleton (Mark Linn-Baker) and his distant cousin from eastern Mediterranean Europe, Balki Bartokomous (Bronson Pinchot).

Originally airing on Tuesdays for the short six-episode first season in the spring of 1986, it moved to Wednesdays in prime time in the fall of 1986. It remained on Wednesdays until March 1988, when it was moved to Fridays. The show found its niche there as the anchor for ABC's original TGIF Friday-night lineup, though it aired on Saturdays for a short time in 1992.

The series chronicles the relationship of Larry Appleton (Mark Linn-Baker) and his distant cousin Balki Bartokomous (Bronson Pinchot). Larry, a Wisconsin native from a large family, has just moved into his first apartment in Chicago and is savoring his first taste of privacy when Balki, a distant cousin from a Mediterranean island, "Mypos", arrives intending to move in with him.

Balki, who was a shepherd on Mypos, interprets what little he knows about the United States by relying on his own (often out-of-context) recollections of American pop culture ("America: Land of my dreams and home of the Whopper"). Balki's signature is his "Dance of Joy", a cross between the do-si-do and the hokey pokey that he performs (with Larry) to celebrate good fortune.

After initially gently rebuffing his cousin's request to stay at his apartment, aspiring photographer Larry decides to take Balki under his wing and teach him about American life; as time goes on, the disparities between the two create many misadventures and growth opportunities. Initially working at a discount store and living in a small apartment, they eventually develop rising careers working for a respectable newspaper, move into larger residences, date two best friend flight attendants, and expand their lifestyle through their various experiences; all while learning to balance Balki's wide-eyed enthusiasm and Myposian ways with Larry's real-world ambitions and American pragmatism. Neurotic Larry is frequently as inept as Balki, if not more so, and often gets the pair into situations that only Balki can set right. Major influences on the show include "buddy sitcoms" such as Laverne & Shirley and Mork & Mindy, both of which were produced by the Perfect Strangers team.

The series was the brainchild of Dale McRaven (co-creator of Mork & Mindy) and producers Tom Miller and Robert Boyett. Miller claimed that the series' inspiration came in the wake of the 1984 Summer Olympics in Los Angeles, when America experienced a wave of renewed patriotic sentiment. Their idea for a comedy about an immigrant in America was initially rejected by all three major commercial television networks operating in the U.S. at the time (ABC, CBS, and NBC).

In December 1984, Bronson Pinchot garnered notice for his role in Beverly Hills Cop as Serge, an effeminate art gallery employee with an unplaceable foreign accent. When Miller and company pitched Pinchot as the star of their immigrant show, ABC signed on to the project, originally titled The Greenhorn. By this time, Pinchot was unavailable, as he had taken the role of a gay attorney in the NBC series Sara alongside star Geena Davis.

Sara failed to find an audience and was canceled by May 1985. With Pinchot now available, Miller and Boyett developed the show in earnest. By November it was retitled Perfect Strangers and comedian Louie Anderson was cast as the immigrant's American cousin. A pilot episode was put into production, but in the end Anderson was not considered right for the role.
