At one point, Golda (Phyllis Diller) tells Henry (Bob Hope), "Boy, did you get a wrong number!" In 1966 Diller and Hope appeared in Völlig falsch verbunden! (1966).

When Dimsdale is standing and talking to his girlfriend in the living room of the house he and the children are hiding in, you can see all the children in the backyard playing.
