Rose: OK, I've got another one. Whenever my kids couldn't sleep, we always sang to them.
Blanche: A lullaby?
Rose: Sort of. "Mr. Sandman."
Dorothy: Oh, I don't know, Rose.
Blanche: Dorothy, come on. It's worth a try. It's either we sing or he sings.
Dorothy: Oh, all right.
Rose: Boom... Boom... Well?
Blanche: Well what?
Rose: After my "boom" comes your "boom," and then yours, until we're all "boom"ing.
