This is the first of many episodes where Lucy gets new furniture. The plot came from the fact that pregnant Lucy was sick and tired of the way the set looked, and she wanted to freshen it up. It also was a way for CBS and Phillip Morris to ensure that Lucy and Ricky weren't sleeping in a single bed in episodes close to the beginning of the pregnancy story line.
We find out that Lucy's phone is on a party line.
Lucy's dressed in loose-fitting clothes throughout the episode, as a way to hide her pregnancy. The dress she wears in the first scene is very billowy, and the overalls were very baggy.
Starting with this episode, Irma Kusely takes over for Bert French as Lucy's hairdresser during the duration of the episodes Lucy filmed while pregnant. Kusely would continue doing Lucy's hair for her later sitcoms, such as The Lucy Show and Here's Lucy.
The LOOK Magazine Ricky was reading in the opening scene is the August 26, 1952 issue. Among its contents is a full-page ad for Phillip Morris cigarettes featuring Desi and Lucy, which just happens to be the page the magazine is opened to when Ricky lifts it up.
