Brain Donors (1992)

Continuity mistake: When Jacques attaches the bungee cord from the cocktail cart to Lazlo's pants, Lazlo takes a step forward and the cocktail cart snaps after him causing a terrible ruckus, however the bottles on the cart mysteriously empty before the collision, and none of them move. They are obviously glued to the cart.

Usherette: Five and six.
Roland T. Flakfizer: Eleven. Now it's your turn: twenty-five and sixty-seven.

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.
