When Ricky rehearses the dance for the "Jezebel" number with Rosemary, he "accidentally" steps on her costume just before it's ripped.
Arroz con Pollo (chicken with rice) is Desi Arnaz's favorite dish.
In season 1, Desi could only sing when the storyline called for it.
Ricky: You know, the funniest thing happened at the club tonight.
Ricky: A strange girl got into the chorus line. She was terrible too!(walks into the closet) She was really ugly, and had the worst figure I've ever seen. And she didn't know any of the steps at all!
Lucy: How could a thing like that possibly happen?
Ricky: I haven't got the slightest idea!
(walks out of the closet wearing the long black wig Lucy wore in the show; Lucy screams)
(Ethel falls on the floor when Ricky opens the door.)
Lucy: Come on in, Ethel.
Ethel: I was just polishing the door knob.
Lucy: I suppose you heard everything.
Ethel: No honey, not a thing.
Lucy: I just quarrelled with Ricky.
Ethel: I don't blame you. Who does he think he is going around tearing girl's black lace blue jeans?
Lucy: Didn't hear a thing, huh?
Ethel: Well I might've caught a word here and there.
Ricky: (about Rosemary's outfit) It's great if we don't get raided.
Ricky: Lucy, you can trust me. I'm as faithful as an old dog.
Lucy: Yeah, Old Rover.
Lucy: (about the item in the paper) Oh Ethel, it's just a publicity story. Ricky is trustworthy, fine, honest, and loyal.
Ethel: Well if he was brave, clean, and thrifty he'd be a Boy Scout. Cat's eye patrol, of course.
Ethel: Look, honey, you don't have to pretend with me. I come to you this morning not just as a landlady, not just as a friend, but as a shoulder on which to weep during this time of crisis.
Lucy: Well. I think you've been twisting those curlers too tight.
Songs: "Jezebel," "El Cumbanchero"
William Frawley did not appear in this episode.
On the original script the title is "Singer" but someone crossed that out and wrote "Dancer".
