Kimble swears in German as he carries his colleague into the house. ("Das macht mich stinksauer! Jetzt bin ich sauer!", which means "That makes me pissed as hell! Now I am pissed!").
The section where Phoebe pretends to be Austrian by sprouting random phrases in German (the language spoken in Austria) was unchanged when the film was dubbed into German. This caused confusion in Germany.
The poem that Kimble reads to the children before naptime is "Spring Morning" from A.A. Milne's book "When We Were Very Young", with illustrations by E.H. Shepard.
Bill Murray and Patrick Swayze were originally offered the role of John Kimble. Danny DeVito was also considered, but was not given the part due to his height.
Arnold Schwarzenegger worked with Pamela Reed again in the movie Junior. Reed portrayed a pregnant woman with a big appetite, quite similar to her character in this movie. He also worked with Danny DeVito in Junior, a candidate for the role of John Kimble, but was not given the part due to his height.
