Three's Company is an American sitcom that aired from March 15, 1977 to September 18, 1984 on ABC. It is a remake of the British sitcom Man About the House.
The story revolves around three roommates, Janet Wood, played by Joyce DeWitt, Jack Tripper, played by John Ritter, and initially Chrissy Snow and later, cousin Cindy Snow, then Terri Alden. They all share Apartment 201 in a Santa Monica, California apartment building owned by Mr. and Mrs. Roper, later owned by Bart Furley but managed by his brother, Ralph Furley, played by Don Knotts.
In "I Am Peter, Hear Me Roar" during a flashback, Peter is watching Three's Company and turns the volume up while Lois is pregnant and dealing with morning sickness in the bathroom. This was used as one of Peter's many examples of insensitivity towards women.
As seen in "I Am Peter, Hear Me Roar", Peter would continue watching television while his wife Lois, pregnant with Stewie at the time, suffers through morning sickness. In the instance seen, he was watching Three's Company. He turns it on at the end of the episode after reverting to his sexist self.
In "Fast Times at Buddy Cianci Jr. High", Peter gets amnesia in a flashback, and he thinks he’s Larry Dallas.
While naming his kids during "Sibling Rivalry", Peter names characters in the Nick@Nite lineup. Mr. Furley is one of those named.
In "PTV", Chrissy appears with her bikini top censored, despite the fact that she was not exposing anything. This scene was one of the first of many as part of the overreaction by the FCC to the David Hyde Pierce trouser malfunction at the Emmys.
In "The Tan Aquatic with Steve Zissou", Mr. Furley walked in on Brian squirting sunscreen onto Stewie. He was horrified because it looked like masturbation. Furley then pretended not to have seen anything and ran away hysterically.
In "Play It Again, Brian", Peter leaves a note for Lois that he was watching a rerun of the show and laughed so hard he accidentally poops his pants. He then goes looking for either an all-night cleaner or a "pants store".
Among the television shows featured in the background during Peter's introduction to ""Family Guy" Through the Years" is an image of Three's Company.
