Corrected entry: When Rodney unknowingly enters the sorority house, he stumbles in on and interrupts a coed (played by Leslie Huntly) taking a shower. When she is first seen and is startled whilst showering, her washcloth is being clutched in her left hand. In the following shot, Rodney walks over and pulls aside the shower curtain, surprising Leslie, revealing her boobs, and also the fact that her washcloth has suddenly changed hands over to her right one.

Corrected entry: When Jason and Derek come back to find Rodney Dangerfield and the chauffeur in their room, Jason introduces Derek as his roommate. However, when they come back to find their rooms transformed into a huge luxurious suite, Jason and Derek go through different doors, as if going into different rooms.
Correction: Rodney obviously used more than one dorm room to create Derek and Jason's 'suite,' and left the original entryways intact - thus, two doors.
Correction: There is more than enough time for her to switch hands while the shot is on Rodney.
