Continuity mistake: In the last skiing scene where Lane is being chased by the paperboy, when the camera is on Lane he has the sleeves to his vest on. The camera then goes to someone else and when it comes back to Lane, there are no sleeves on the vest, then they are back on again later.
Continuity mistake: Lane goes to his first day of work at "pig burger". A closeup is shown of the owner's mouth as he snarls "Myers...". There's about 1/4 inch of facial hair all over his face. When they cut from the closeup and show the rest of his body you can see that he's fairly well shaven, only some 5 o'clock shadow.
Continuity mistake: In the scene where Monique is introduced to Ricky at in the movie you see Ricky remove the red cap of his nasal spray and drops it as he goes to spray it in his nose. When the Camera zooms in on the next shot of him snorting nasal spray you can see him drop the red cap again.
