Trivia: When Lucy was pregnant with Little Ricky, CBS would not allow the word "pregnant", so "expecting" was used instead.
Trivia: Did you know that the original names for the Ricardos would have been Lucy and Larry Lopez? In the lost pilot episode, the voiceover says "You are about to see the pilot episode of the show that was almost I Love Lopez."
Trivia: On January 19th 1953, when Lucy Ricardo gave birth to Little Ricky on I Love Lucy, which 68% of U.S. TV sets tuned in to watch, Lucille Ball also gave birth to Desi Arnaz Jr. (in a planned C-section) on the same night. Newborn Desi Jr. was featured on the very first national cover of TV Guide. As a strange coincidence, on January 19th, exactly 43 years later, Marlee Matlin gave birth to her daughter at the same time that the evening's episode of Picket Fences was being aired, and her character on the show, Laurie Bey, was giving birth to a son.
Trivia: I Love Lucy was the first TV show to shoot episodes on high-quality film, rather than cheaper video tape. The network was opposed to this more expensive shooting method, but Desi Arnaz struck a deal with them that his production company, Desilu, would pay the extra costs in exchange for ownership of the filmed episodes. In what is considered one of the most lucrative deals in television history, Arnaz and Lucille Ball made millions of dollars from rerun residuals.
Trivia: When Lucy's reading the book about infant care, she's holding a baby doll wearing a bonnet in order to learn how to bathe and diaper a baby, and the doll she's using is not just any prop. It's actually one of the show's endorsed products named the "I Love Lucy Baby" doll, which were sold in stores.
Trivia: When Mr. Willoughby puts on his bellboy hat he shouts, "Call for Philip__," and stops short, then adds that he's "heard that a thousand times but just can't remember the fella's last name." The sponsor of 'I Love Lucy' was Philip Morris Tobacco Company, whose popular ad campaign at the time was a bellboy who shouted, "Call for Philip Morris." (00:17:10)
Trivia: I Love Lucy was the first TV show to use the three-camera filming technique. It was developed by cameraman Karl Freund and Desi Arnaz, who was the show's producer as well as its co-star. Cameras were placed center stage, stage right, and stage left. The film footage was later edited together to show the action from different angles. This method is considered standard and is still in use today.
Trivia: Right after hiring the maid, when Lucy's sitting on the couch she's reading Companion magazine, and on the cover of this issue there's a small inset photo of Lucy, Desi, and Desi Jr. This magazine is seen again in "Lucy Wants New Furniture" when she has dinner set up in the living room, and is waiting for Ricky to walk in.

Trivia: When Ricky tells Lucy to sit down and rest before the "surprise" baby shower, Lucy opens a McCall's magazine and on the cover it reads "I Love Lucy" though the cover has been altered a bit. This issue of McCall's is from January 1953, and the cover actually reads "Why I Love Lucy, by Desi Arnaz", which includes the article that was written by Desi. (00:05:15)
Trivia: Before Lucy begins her first rehearsal for the Vitameatavegamin commercial, the director calls out, "Maury, will you stand by with the script, please," and Maury, the script coordinator, takes a seat in front of Lucy with his back to the camera. Maury is played by Maury Thompson, who was the real-life script coordinator for "I Love Lucy" during the first season, before becoming camera coordinator. (00:10:50)
Trivia: When Ricky's on the air as the host of "Your Saturday Night Varieties" he tells the audience that he will start things off with a little music, and before he begins to sing he looks offstage and says, "Mr. Hatch, if you please" to cue the start of Ricky's music. Wilbur Hatch is the name of the real-life music composer and orchestra conductor for "I Love Lucy." (00:22:05)
