Continuity mistake: In season 2's episode "The Ricardos Change Apartments" their new apartment number is "3B", but in this episode when Lucy's at her audition she tells the casting agent that her apartment number is "3D" (deliberately done in order for the 3D joke to work), and it's in the next episode "The French Revue" that we see the new number "3D" on the door. (00:19:30)
Visible crew/equipment: When Lucy and Ethel are at Caroline Appleby's apartment, a few actors' tape marks are visible on the carpet near the couch and side table, where characters will stand at different times during the scene. (00:06:00)
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.
