How Well Do You Remember "The Mary Tyler Moore Show"?

In the first episode of the TV series, Mary Richards is introduced as a newly single 30-year-old woman who is looking for a fresh start after breaking off an engagement with her fiancé.

For the majority of the show, Mary Richards lives in a third-floor studio apartment within a quaint 19th-century house. Once fans discovered the real Minneapolis house that was used for the show' exterior shots, it became a popular Minneapolis tourist spot.

"Love Is All Around" was released as a single in 1970, and then again in 1980 on Sonny Curtis's album, "Love Is All Around." The latter version featured a country arrangement and reached number 29 on the Billboard Hot Country Singles chart.

Although Mary initially applies for a secretarial position at WJM, she is offered a job as associate producer of "The Six O'Clock News." She's promoted to producer in the show's fifth season.

While Lou and Mary became very close during the run of the show, their relationship was never romantic. Lou does briefly date Rhoda, however, in the season four episode, "Lou's Second Date."

Lou says this to his new hire Mary in the first episode of the series, which is entitled "Love Is All Around." "Love Is All Around" is also the name of the show's popular opening theme song.

Mary's parents made their first appearance in the season three episode "Just Around the Corner." Played by Nanette Fabray and Bill Quinn, the pair move into a house around the corner from Mary and start meddling in her personal life.

In addition to jokes about Chuckles' death, this episode also features the hilarious "Credo of the Clown" poem, as recited by both Ted and the reverend at Chuckles' funeral. It goes, "A little song, a little dance, a little seltzer down your pants."

While parts of the show's opening sequence changed as the years went on, it always ended with Mary's famous hat toss. The theme song, which was written and performed by Sonny Curtis, also remained the same.
