Send a Gorilla(1988)

The girls and gorillas at a singing telegram company are overworked because it is Valentine's Day. A series of sub-plots - a sexist disc jockey loses his dog and the girls fine it; one of the girls fights for custody of her child; an aspiring opera singer gets her chance to audition; and evil developer demolishes the telegram company's offices, etc, which all adds up to a large dose of confusion.
