The next morning, Betty discovers they're out of melba toast, prompting Don to snit at her she should eat something more substantive anyway. Not really listening, Betty speculates that Carla had some, because Betty would have thrown the empty box away if she'd been the one to finish it. Don is not interested in the Mystery of the Missing Melba, however, instead giving Betty shade for apparently spending too much on a decorator for the imminent child's nursery, I think. After a promise to the kids that some boring shopping the next day will be followed by a trip to Carvel, Don's out of there, leaving me to wonder if that scene could possibly have been cut.
