Continuity mistake: At the end of the movie, Spence is seen with Claudia in a western movie. He walks through the swinging bar doors with a cigar in his mouth. He takes a few steps forward and the size of the cigar has nearly doubled.
Continuity mistake: The damage to the front grill of Binkey and Turnip's first caddy changes throughout the car chase with Spence and Dennis from a small hole to half the grille.
Continuity mistake: When Spence's brother in-law almost crashes into Dennis' girlfriend's car, he's driving straight down the road and she makes a left from the intersection to cut in front of him, but when the camera angle changes back to the inside of the brother in-law's car the intersection that he should have just passed is nowhere to be seen.
Continuity mistake: When Dennis and Spence are trying to outrun the cops in the car that Spence stole from the racetrack, the camera shot from the inside shows them driving on a regular street with the yellow lines and everything but the camera shots from the outside show them driving on blacktop streets with no lines whatsoever.
