Return Home From Europe - S5-E26
Continuity mistake: As Lucy gets up from her airplane seat holding the big hunk of cheese wrapped in a blanket she is masking as a baby, it bends in half as if it were already cut. This is the scene before she sneaks off to the kitchen to cut it apart. In prior scenes, the cheese is intact and solid. (00:17:10)
Character mistake: Bob Hope mistakenly calls Lucy "honey" when she's dressed as the intrusive hot dog vendor. He was supposed to believe she was a man. (00:12:00)

Little Ricky Gets Stage Fright - S6-E4
Continuity mistake: In the first 5 minutes of the episode, the necktie of Fred Mertz changes length several times. Sometimes it touches his belt, in other times, both ends are the same size. (00:02:00 - 00:03:20)
Continuity mistake: During the scene set in the boat there is no land seen, but in the shots outside the boat, the land is present. In the same scene Ricky is wearing a wide-collared shirt but in the location part, he is shown wearing a white T-shirt.
Continuity mistake: In this episode, Lucy goes out on the window ledge. In "Lucy Cries Wolf", the window ledge was very different: the walls were made of dark brick instead of concrete blocks, there was no downspout, and the ledge went into the corner and stopped, no continuation on the other wall.
Continuity mistake: In the scene where Superman comes to Little Ricky's party Little Ricky has on a birthday hat. When Superman picks him up the hat is gone; it reappears when Superman gets ready to leave.
Revealing mistake: While Lucy is out on the ledge, if you look at the pipe as it runs from above the ledge to below it, the two pieces of pipe don't line up. They are off about the full diameter of the pipe. Also when the pipe pulls out, it's obvious the pipe is on a hinge at the bottom and not really attached to the lower pipe. Later, there is also no stream of water falling from above where the pipe was supposed to be connected as a drain even though it is pouring out.
Continuity mistake: When Lucy buys back her coffee table, Ethel and Fred move it to the kitchen in the Mertz's apartment. The door to the Mertz's kitchen (with its doorknob on the right) in this episode opens the opposite way, inward towards the inside of the kitchen, and not outward in the direction of the living room, as seen in all previous and following episodes, including the very next episode. (00:17:55)
Continuity mistake: In the episodes where Lucy and Ricky are Getting Ready to move to the country, there are shots in the Ricardos' bedroom that shows a wall on the right hand side of the room. In previous episodes, there was a window where the wall appears during the later 'moving to Connecticut' episodes.
Visible crew/equipment: When little Ricky enters the living room, you can see a man's hand quickly open the door for him. (00:19:20)
Visible crew/equipment: When the chicks are running loose in the living room, and Lucy, Little Ricky, Fred and Ethel are trying to corral them, you can see the chicken wire and braces set up to keep the chickens on the set. (00:20:20)
Other mistake: In the first scene when Ricky staggers down the stairs and on his way to work it's supposedly first thing in the morning but the hands on the Grandfather clock are at 12 Noon/Midnight. (00:00:45)
Continuity mistake: When Lucy and Ricky are discussing the dance at the beginning of the episode and she turns away from him after she tells him "that's all there is to it," however in the next shot she is still facing towards him.
The Ricardos Dedicate a Statue - S6-E26
Continuity mistake: When Ricky is angry toward Lucy that Little Ricky's pet dog Fred has not learned to be obedient he threatens to return Fred to the dog pound where he says the Ricardos originally got him. However, in episode "6-12", Little Ricky Gets A Dog" Little Ricky admits to Lucy that he got Fred from one of his playmates whose dog had puppies.
Suggested correction: The kitchen is a double hinged "saloon style" door. The door opens both ways, just like in a restaurant and most kitchens of the era. This is evident in many episodes.
You're confused. Rewatch the episode, please. Your correction is describing the Ricardo apartment; it's Ricky and Lucy who have the kitchen with that swinging door, which you describe as "double hinged saloon style" that opens both ways. This mistake is actually referring to the Mertz's apartment, and their door leading to their own kitchen is a standard door with a doorknob and it always opens only one way - outward into the living room. It's only in this specific episode the Mertz's kitchen door is attached to the door jamb differently, and it opens inward into the kitchen. The mistake is absolutely valid.
