Joanie Loves Chachi is an American sitcom television series and a spin-off of Happy Days that aired on ABC from March 23, 1982, to May 24, 1983.

The series is set in the early to mid-1960s and follows the exploits of Joanie and Chachi as they moved to Chicago and tried to make it on their own with a rock band and a music career at a time when the British Invasion was looming (one episode was titled "Beatlemania").

Their backup band consists of a spaced-out drummer named Bingo and Chachi's blasé cousins Mario and Annette.

Like other Garry Marshall-related sitcoms such as Happy Days and Laverne & Shirley, Joanie Loves Chachi had its share of anachronisms.

An urban legend circulated that the show was the highest-rated American program ever in Korea due to "chachi" being a Korean word for "penis".

Chachi believes that, specifically, men are better than women at basketball, so Joanie challenges him to go one-on-one with her female friend who plays on the school's team.

To avoid being seen by Joanie as she and other students enter the room, he tells the teacher that he is the model and soon learns that he will be posing nude.

After repeatedly being warned about showing up late for and taking excessive breaks during performances, Al and Louisa are left no choice but to fire the band.

After seeing how much in love Louisa's aunt and uncle are after 50 years of marriage, Joanie and Chachi decide to elope.

[4] The show debuted as a mid-season replacement and initially attracted high ratings, benefiting from two factors: it aired immediately following its parent series, Happy Days, and had only reruns competing for its time slot.

[1] The ratings plummeted in Season 2 with a move to Thursday nights, which put Joanie Loves Chachi up against CBS' Magnum, P.I., and it was pulled from the schedule by the year's end, with its final two episodes airing in the spring of 1983.
