Roland T. Flakfizer: And she looks like she's about fifteen. Lazlo: No, no, no. Roland T. Flakfizer: Okay, fourteen then. In fact I know she's fourteen, because I was dating her a year ago.
Usherette: Five and six. Roland T. Flakfizer: Eleven. Now it's your turn: twenty-five and sixty-seven.
Continuity mistake: In the scene in Lilian's town house, when Laslow is searching Lilian's room looking for Tina, Flakfizer intentionally sneezes into talc powder. Barring the cheesy effect of it flying all over the place, his arm (and body) alternate between being covered in powder and being clean. He ends the scene being clean.
Trivia: The film was originally shot under the title "Lame Ducks" (hence the animated duck in the movie's title sequence), and studio Paramount was going to give it a tremendous marketing push, hopeful that it would kick-start an ongoing comedy series. However, the Zucker Brothers, who were the main producers of the film, had a falling out with Paramount and left the studio during post-production. Paramount purposely sabotaged the film's marketing and changed the title in a bid for retribution. It bombed at the box office, but thankfully subsequently made a profit on home video as a sleeper-hit thanks to positive word-of-mouth.
