California, Here We Come! - S4-E13
Visible crew/equipment: When they're all finally in the Pontiac ready to leave NYC, just as Ricky starts to drive away we can see cables jiggling under the Pontiac, to the left of the front tire, pulling the car. Funny to see how Ricky puts his hand on the gear stick, but never actually does anything with it. (00:23:40)
Visible crew/equipment: While Ricky and Fred are trying to clean up the volcanic rice eruption, when Ricky slips on the floor the second time the front edge of the raised kitchen set's platform can be seen. (00:19:15)
Visible crew/equipment: During the scenes at the small diner when it's open for business, such as when Marco walks in, there are two small chalk T-marks on the floor in the area near the door. The T-marks are also visible when Ethel and Fred walk back inside. (00:12:35)
Bonus Bucks - S3-E20
Visible crew/equipment: After Ricky sneaks the dollar bill into Lucy's purse he sees her stirring in bed, and when Ricky ducks down to hide from Lucy, the two curved chalk actor's marks are visible on the carpet. (00:07:15)
Never Do Business With Friends - S2-E32
Other mistake: When Lucy and Ethel are on the back porch fighting about the washing machine and also when Mrs. Trumble walks out, Lucy's back door is open and we can see the shutters between the kitchen and living room, with the kitchen counter/sink underneath, but the sink's faucet which should be seen has vanished. (00:14:45)
Lucy Wants New Furniture - S2-E28
Other mistake: When Ricky corners Lucy while she's holding the box of salt, the top and sides of the box have tape hiding its brand name (looks like Diamond), to prevent it from being seen on the air. (00:13:30)
Visible crew/equipment: When Ethel's on the stoop in front of the building waiting for Lucy and Ricky, right before Ethel asks Ricky about Lucy's driving lesson, just as Ricky drives up we can see cables moving in front of the new Pontiac pulling the car. Then, when Ethel crashes the new Pontiac into the old car, the jiggling cables are again in front of the new car. Lastly, when Lucy finally starts the old car's engine, now there's a moving cable in front of the old car as well. (00:09:50)
Visible crew/equipment: When Lucy opens the closet door to show Ethel all the donated stuff for the bazaar auction, the boom mic (appears to be a double mic) dips down into view at the top of the screen (not visible in some streaming versions). (00:02:25)
Visible crew/equipment: After Lucy tells Ethel her plans for gluing on a mustache, Ethel congratulates her on the crazy idea, and in the next shot of Lucy in her bedroom just as she opens the door for Fred and Ethel, a crew member's arm moves into the shot at the right side of the screen. (00:06:15)
Lucy Is Jealous of Girl Singer - S1-E11
Visible crew/equipment: After Lucy goes into the bedroom with the newspaper and raises the window shades, when she walks around to Ricky's side of the bed, a crew member's shoulder/arm moves into the shot at the right side of the screen. (00:04:10)
The Séance - S1-E7
Visible crew/equipment: After the first shot of Mr. Merriweather trying to contact Tilly on his ouija board, when it cuts to him answering the telephone we can see the moving shadow of the boom mic, on the door to the right.
The Girls Want To Go To the Nightclub - S1-E2
Visible crew/equipment: When Lucy and Ethel are talking about going to the Copacabana, just as Lucy leans toward Ethel before her remark about catching more flies with honey, the second camera/equipment can be seen at the right side of the screen. The same thing happens later, when Ricky laughs at the idea that Lucy and Ethel will have dates, as Ricky walks over to Fred standing at the desk, camera/equipment is visible at the bottom, right corner of the screen. (00:01:45)
Visible crew/equipment: After Lucy and Mr. Beecher sign the lease, just as they all start heading toward the door, the taped T-mark is visible at the bottom of the screen at the edge of the carpet (presumably for the second camera dolly offscreen at the left). Then as Mrs. Hammond walks out, a bit of overhead set equipment can be seen at the top right side of the screen. (00:12:45)
Continuity mistake: While tired Lucy is trying to open the card table's legs, she lays her head down then falls asleep, and when it cuts to Ethel and Fred walking in on our sleeping Lucy, there's writing on the table's underside which wasn't in the previous shot. (By the markings on the table it also looks as if the table has been turned on its adjacent side). (00:06:10)
Visible crew/equipment: After take one of Ricky's Screen Test, when the director says to Lucy, "I thought it might add interest to the scene if you could make it go around and around like a lighthouse!", the Ricardo's kitchen cupboards and fridge are visible off stage to the left of the director's head.
Redecorating - S2-E8
Revealing mistake: At the end of the episode, when Ricky and Lucy walk into the bedroom to see the new wallpaper, look behind them when the bedroom door opens and you'll catch a glimpse of William Frawley - waiting for his cue - hiding behind a wall in the background before he ducks back out of sight.
First Stop - S4-E14
Visible crew/equipment: After driving all day, the Ricardos and Mertzes stop by a run-down diner then end up spending the night in their shared cabin. While they're all in their beds, the vibration of the nearby train causes the Ricardos' bed to shakily slide towards the Mertzes and then back again. The wires attached to the Ricardo's bed are visible, coming from the hole at the bottom of the left wall, and the leg at the foot of the bed is set in a track attached to the floor, which keeps the bed on course.
The Anniversary Present - S2-E1
Deliberate mistake: In this episode Lucy is trying to get Ricky to notice that their anniversary is on Monday the 19th by showing him a large calendar with the 19th circled. However, when they are in California and they celebrate their anniversary and Ricky asks for information to be wired to him, the telegram tells him that their anniversary is on the seventh.
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.
Lucy Thinks Ricky is Trying to Murder Her - S1-E1
Visible crew/equipment: When Ricky walks over to the table while he is on the phone with Jerry, a camera is briefly visible on the right hand side of the screen. (00:08:15)
Answer: According to Snopes.com, there is no definitive answer, but the mid-1960s is the most verifiable date with "The Munsters" being cited as the first, although others claim "The Brady Bunch" showed the first couple seen in a double bed. An early TV show from the late 1940s titled, "Mary Kay and Johnny" is also thought to have shown the married couple's bedroom as having a double bed, although probably not with them in it. However, this was when TV was aired live, and there are no surviving episodes, only anecdotal accounts.

Something that is funny is that in the movie "A Christmas Story," they show the parents having two twin beds in their bedroom. In a real situation, they should have shown them having a double bed. Lucy and Ricky had twin beds pushed together in an early episode, which would have been pushing television boundaries in that time.
