When Doug and Steve are getting ready in the bathroom to go to the Roxbury that night, at one point they take plastic strips and remove the hair off each other's back. Well, look closely at the plastic strip on Doug's back because when it is supposed to be stuck on there ready to rip off, it looks like it is hanging on to his back by a thread and is not even really attached. The sound effects just make it seem like it's being torn off it's back. It looks so fake.
