Rob (Dick Van Dyke) and Laura (Mary Tyler Moore) go out of their way to be friendly to their new neighbors, Fred and Mary Jane Staggs (Joby Baker, Sue Taylor).

Listen for the voice of Carl Reiner in the climactic gag involving the clandestine recording of a wretched off-Broadway musical. ~ Hal Erickson, All Movie Guide
