The bathrobe that Ethel wears while digging through the bar-b-que is the same bathrobe that Ann Margaret will wear in an episode of Here's Lucy.
Lucy: Now Ethel, I'd do it for you if you'd lost your wedding ring.
Ethel: If I lost my wedding ring, we wouldn't have to find it. We'd just have to buy another box of Cracker Jack.
Little Ricky: Daddy, let's fly my new kite.
Lucy: (frustrated) Yeah, go fly a kite.
Ricky: When we got married, you said you will never take your ring off.
Lucy: When we got married you said that dish water would never touch these lily white hands.
Ricky: Well, I bought you a pair of rubber gloves, didn't I?
Lucy: What is that?
Ricky: A piece of lint. You must have missed it with the carpet sweeper.
Lucy: Thank you very much.
Ricky: What do you want me to do with it?
Lucy: Why don't you get yourself a scrapbook and start a lint collection?
Lucy: (to Ricky) Honey, why don't you call up little Freddie Mertz and ask him to come play with you.
Ethel: Oh, it's times like this I wish I'd have kept a diary.
Ethel: Just so I could write "Dear Diary, Tonight I went out in the backyard in my nightgown and felt wet cement".
When everybody is looking at the rebuilt barbecue
Fred: Well, I'll be a monkey's uncle!
Ricky: (shouting) NEVER MIND ABOUT YOUR RELATIVES!
Ricky: (to Lucy who has lost her wedding ring) I'll buy you a new ring with big diamonds all around it.
Lucy: (weeping) I don't want a new ring with big diamonds all around it. I want my old ring with the little diamonds half way around it.
Ethel comes back to help Lucy finish putting the BBQ back together.
Lucy: Gee, Ethel, thanks. It's times like this when you know what friends are for.
Ethel: If I had known this is what friends are for, I would have signed up as an enemy.
Fred: Ethel did you take part in these shananigans
Ethel: Yeah I did, and I'm dead tired from being up all night lifting them heavy bricks and if you say one more word to me about it Fred Mertz I'm gonna take you apart and put you back together again!
Fred: I just asked, Honeybunch.
In real life, when Lucy and Desi eloped in 1940, he bought her a brass ring but later had the same ring recovered in platinum.
