In "The Seven Year Itch", Tom's wife and son are in a fantasy segment he's having, they're on a trip to a resort, and on the dock is what looks like an Emerson portable tv with a color picture. Marilyn Monroe as the girl upstairs does her Dazzledent toothpaste ad, then tells the views about the horrible man downstairs from her that attacked her.
