Lucy Is Jealous of Girl Singer - S1-E11
Revealing mistake: During the rehearsal for the Jezebel number, the dancer's skirt trim is already partially torn or unattached to make it easier to tear, and it is clear that Ricky purposely steps on the trim to rip it off the skirt.
The Ricardos Are Interviewed - S5-E7
Visible crew/equipment: When Ricky's new agent stops by the apartment to talk to him, Fred and Ethel are standing in front of the desk, and there's a T-mark on the floor in front of Ethel's feet. (00:04:50)
Homecoming - S5-E6
Visible crew/equipment: During the episode a small tape mark is visible on the floor between the coffee table and the couch, and a T-mark can be seen on the floor near the desk, such as when Lucy starts telling her guests about their "fabulous" trip, Ethel stands at the T-mark and a female guest stands at the tape mark. (00:07:05)
The Great Train Robbery - S5-E5
Revealing mistake: When Ricky and Lucy find their train compartment, while they stand outside their door talking we can see the actor playing the porter peeking out of the next compartment's door waiting for his cue, and in a few moments he opens the door just as Lucy approaches. (00:02:20)
Visible crew/equipment: When Ethel walks into her hotel room and tells Lucy and Fred about having to push the motorcycle to three different places, the second camera (or other equipment) keeps moving in and out of shot at the right side of the screen. (00:13:00)
Don Juan and the Starlets - S4-E18
Continuity mistake: After the maid sees Lucy sleeping on the couch and leaves, in the next shot the clock reads 10:00 and Lucy wakes up, but when Lucy checks the bedroom and walks back into the living room, the clock now reads 6:40. (00:16:25)
Continuity mistake: At the start, when the Pontiac convertible turns into the driveway of what should be the Beverly Palms Hotel, the sign with the real name of the hotel can be seen, which reads Beverly Carlton Hotel.
First Stop - S4-E14
Continuity mistake: When Ricky stops the car and backs up trying to locate Aunt Sally's, Lucy gets out of the car wearing a coat and a pantsuit underneath, but in the exterior shot she's wearing a skirt set when she walks over to the shed to read the sign. (00:03:50)
California, Here We Come! - S4-E13
Revealing mistake: The Pontiac's glass windshield is gone when the car is loaded down with everyone's stuff, thanks to Fred's packing, and the windshield is also very noticeably gone when they all finally drive off. The rearview mirror, which should be attached to the windshield frame, is gone as well. (00:20:30 - 00:22:50)
California, Here We Come! - S4-E13
Visible crew/equipment: When "Mickey" takes his mother-in-law's suitcases to the back, just as Lucy and her mother sit down on the couch, we can see the bright shadow of something moving across the piano behind them. (00:06:50)
Visible crew/equipment: When Lucy and Mrs. Littlefield bring out the soup and then salad, at the start of the shots just as they leave the kitchen, the shadow of another camera can be seen on the edge of the set's "wall" at the right side of the screen. (00:20:25)
Visible crew/equipment: After Lucy phones Ricky and fibs about a man being on the fire escape, when Ethel and Fred rush in looking for Lucy, two actors' tape marks are visible on the floor where Fred and Ethel stand, beside the couch. (00:06:20)
Visible crew/equipment: While Ethel and Lucy are trying to frighten Mr. Beecher so he'll leave the apartment, when Lucy blows up the balloon the reflections of all the overhead set lights are visible on the balloon. (00:23:00)
Tennessee Ernie Visits - S3-E27
Continuity mistake: When Fred and Ethel leave to get the rollaway bed, note the two L-shape actor's marks on the carpet where Ernie had placed his small suitcase and then sat, earlier in the scene. (00:08:50)
Visible crew/equipment: During the scenes in the living room after wig-wearing Lucy comes home in a huff about Ricky, an actor's mark is visible on the carpet at the fireplace, and there's a T-mark on the carpet between the couch and desk.
Visible crew/equipment: When Lucy and Bert (Roberta) walk into the back of the salon, there are a few chalk marks on the floor to the right of the styling chair, and a few moments later that's where both Doug and Bert stand when Doug doesn't recognizes Lucy at first. (00:03:40)
Other mistake: When Ricky and Fred hold up the newspapers with the big holes in the back page, we see the front page with the headline "Bond Issue Defeated", and it should look familiar since it's the same front page that was used in the episode "Ricky's Old Girlfriend", with the article about Carlotta Romero. (00:18:15)
Visible crew/equipment: When Lucy tells Ricky, Fred, and Ethel that she made a carbon copy of the novel they just burned in the fireplace, the actors' tape marks are visible on the carpet when Lucy says, "Pardon me," in the wideshot. Then later, when Ricky, Fred, and Ethel walk in while Lucy's typing up her sequel, they stand at tape marks again. (00:11:05)
Visible crew/equipment: While Lucy starts taking notes about Ethel, Fred walks in and soon asks, "What's going on this booby hatch," then just as Lucy rushes back to the desk, we can see the end of the set wall and there's some kind of partition in front of the kitchen set. (00:02:35)
Continuity mistake: When Martians Lucy and Ethel are sneaking up behind everyone on the Empire State Building, in the closeup Ethel has a toy gun tucked into her belt just as she climbs over the fence, but in the next wideshot her toy gun is already lying on the observation deck floor. (00:17:25)
Chosen answer: It's not known. She may have moved it to the spare room or it may be in a corner just off camera. There could be any number of reasons, though it probably took up too much room on the studio set, and it was removed, making it easier for the actors to move around.
