The Operetta - S2-E3
Revealing mistake: Near the end when the repossession men are taking away the costumes and scenery, as they are removing Ricky's pants one of the chorus members can be seen waiting backstage for her cue to enter screaming.
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.
Lucy Goes to the Hospital - S2-E21
Revealing mistake: When Ricky, Fred, and Ethel are rehearsing the hospital run, we can see the area to the left and right of the couch, as well as the back wall by the desk. The problem is the telephone cord doesn't actually lead anywhere, it's just coiled up under the couch and not connected to anything. When Lucy says it's time to go to the hospital, Ethel uses the phone to contact the doctor but gets a busy signal, which would be quite impossible. (00:09:55)
Lucy Wants New Furniture - S2-E28
Revealing mistake: When Ricky startles Lucy in the kitchen just as she's getting the salt, she climbs up through the kitchen/living room window, and in the shot from the living room when she and Ricky step down onto the chair, we can see the four long metal brackets which bolt the chair to the floor for safety. (00:13:15)
Revealing mistake: After Ricky and Lucy split up to go fishing Ricky yells that she should watch out for bears, and when Lucy stops at a tree and crouches down, the huge tree beside her jiggles when she leans on it. (00:13:40)
Answer: There is no reason. It's a just a silly plot device, typical of the era. Women characters were often portrayed as making uninformed assumptions or decisions.
