A scene in the film explains Pat's sex with Japanese subtitles. It then had a worker walking in front of the subtitles while vacuuming so that Pat's sex could not be determined by viewers. When shown on television now the subtitles are no longer included.
After Pat gets fired from looking into people's mail, he walks into the store to get a few personal items. When he's talking to Tippy about getting the personal items, the eye dropper and the deodorant stick disappear and reappear between shots. Tippy puts the eye dropper and the deodorant stick inside the bag three times. The bag clearly contains three of everything, except the napkins.
At the beginning of the movie, Mrs. Riley's obstetrician tells her she is the mother of a 7-1/2 pound baby. The birth certificate Pat shows Kyle later in the film displays a birth weight of 8 pounds, 2 ounces.
