Toward the end of the episode, before Ann shoots the commercial with the train, she lies on a stretcher draped with a blanket that has a checkered decorative border. This is the same blanket that covered Rob and Laura's beds on The Dick Van Dyke Show.
The commercials that Ann shoots are similar to the real-life 1967 Dodge Rebellion commercials for General Motors where the spokes model, Pamela Austin, was placed into dangerous situations to promote the product.
The train that was about to hit Ann was stock footage of a Louisville and Nashville Railroad passenger train.
