At the end when the group propose a toast, the blood under Danny's bottom lip appears and re-appears between shots.
Stacie and Danny go to the Human Resources desk to access the staff directory. Danny goes to distract the girl at the desk, while Stacie turns the computer monitor around to use it. As she begins to turn it towards her, there is a mouse on the counter that wasn't there in the previous frames.
The opening credits show a drawing of a D6 die floating down from top of screen. As the D6 die descends, all sides of the die are shown. The error is the fact we see the "1" pip and the "6" pip on adjacent sides next to each other when the "1" pip and "6" pip should be on opposite sides. On a D6 die opposite sides will always total "7". This error would apply to every episode using the same opening credits presentation.
