This episode marks the first, but not the last, of Lou's marital woes coming in part because of his wife Edie's need for fulfillment and accomplishment in life, particularly as empty nest syndrome settles in.
Continuity Goof: According to this episode, Marie Slaughter is 7 months pregnant. But in "Just a Lunch," which aired only 2 weeks earlier, Marie is not pregnant.

This episode features the famous shot of Mary hugging Lou, Murray, and Ted, accidentally crushing Ted's hat. It was featured on the opening credits starting with Season 2. This scene was updated and re-filmed for the credits starting with season four.
It is revealed in this episode that Mary's annual income the year prior was $8,000. That would have been roughly the median for women in 1970, depending on age and demographics.
This is the first MTM episode where the closing credits roll on top of an actual scene (Ted's acceptance speech in the middle of the newsroom as everyone rolls their eyes and walk away). This would eventually become standard sitcom practice two decades later, employed by Roseanne, The Drew Carey Show, Ellen, etc.
The "Tinker Award" that Lou gives to the newsroom staff at the end of the episode was presumably named after Grant Tinker, the head of MTM Enterprises and who was at the time Mary Tyler Moore's husband.

In this episode, it's revealed that Mary's mother's name is Marge.
The outdoor sequence with Mary and Bess was actually shot in downtown Los Angeles around the Century City Mall.
Goof: Howard said that it was no big deal that the film in his camera was exposed, it was only pictures of a total eclipse of the sun. Considering it was 1970, the film in his camera would have been very old since the prior eclipse that occurred in Minneapolis was June 30, 1954.
Richard Schaal, who plays the role of Howard, and later in the series the role of Howard's brother Paul, was married to Valarie Harper during this time.
This begins the "Battle of the Bulge" for Rhoda, with lines like "I gotta lose 10 pounds before 8:30" and while eating snacks from a bowl, she sees that her date is a newlywed with a beautiful wife and then DUMPS all the snacks out of the bowl into her lap, and starts shoveling them into her mouth.
