When Bartleby takes Monica back to his room he hits himself with the door which is clearly in an open hallway and opens from the right. In the next cut the door opens from the left and is in an alcove.
When Bartleby receives the letter telling him about the meeting with the state board of accreditors, the letter says that the meeting is at 11am. But, when Bartleby and company arrive for the meeting, they tell the receptionist that their meeting is at 3pm.
When Sherman is in the room with the pool table, he backs into the rack holding the pool sticks and knocks them down. In the next shot back to him, there are 2 sticks and the 9-ball rack back on the rack.
The board that all the student write the courses on throughout the movie is different from the board brought into the meeting with the state board of accreditor. The board is smaller and some of the courses that were written on the other board are not there.
When B. is giving the speech at the end to the Board of Directors, at the end of the speech he throws the chair that is in front of him onto the ground. In the next scene you can see the chair still in front of him, then you see someone picking it up off the ground.
When Hands throws the cheques on the table in front of Sherman, the movie goes on with the group discussing what they are going to do. Whenever the screen shot is back on Sherman, during the discussion, the pile of cheques are always in a different spot on the table.
When Hands and B are sitting playing computer games, Hands' right shorts leg is above the knee, the camera angle changes and we see them still playing games from behind, when the camera moves back the shorts are now covering his knee.
When Monica first visits South Harmon, she comments how difficult it was to find the building, with Batleby responding "We're a pretty well kept secret." Yet, at least 300 college rejects seem to of found the location after being "accepted" fairly easily earlier in the film. And Ambrose finds it just as easily when looking for the building's leaseholder.
In the scene where the Dean of B's University is lecturing to a large group of students in the center of the half-pipe, there is a black "X" near his feet (his mark), but in the very next scene it has been removed.
When Bartleby is explaining to Hands, Glen, and Rory why they should get accreditation, right before Sherman shows up, the wall behind him has "Yen Chi..., Chinese Restaurant" painted on it with a phone number. This number belongs to a Yen Ching Chinese Restaurant in Burbank, California.
When the fire alarm is activated at the party all the sprinkler heads activate and spray water. Automatic sprinklers use a metal alloy with a low melting point to govern activation. Only heat can activate a sprinkler head.
After Ambrose sets off the sprinkler system and the whole party decides to continue, nobody is electrocuted from the band instruments and equipment and such which are obviously plugged straight into the outlets.
