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.
This episode can be seen as the prototype for Mary's disastrous dinner parties. In this episode, the guests all show up expecting dinner, which Mary hasn't prepared as she thought the late start time of the gathering would let them know that dinner would not be served.
Goof: When Mary is telling Rhoda about being called a "ma'am" they are eating dinner at the table.

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).

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.
Mary and Lou discuss other stations in competition for the "teddies" and mention WCCO, which is a television station in Minneapolis/St. Paul that was the news ratings leader during the 1970s.
