Continuity: During the scene when Van and his friends are riding in Van's golf cart, just after Van has sex with the secretary, the guy in the back is seen being licked on the face by the bulldog. When the camera cuts to Van he's not being licked. When the camera cuts to Van's assistant he's being licked again. This happens over and over. (Time)

Continuity: At the beginning, the Asian woman appears to be performing oral sex and from the shot behind her her hands are grabbing Van's pant legs, but when they reveal what she is really doing suddenly she has a measuring tape in her hands.

Continuity: In the last scene, at Van Wilder's party, Gwen is talking to Van Wilder and her bathing suit strap is on her left shoulder. When the shot changes, it has disappeared from her shoulder and is on her back. She wouldn't have moved it as her hands don't move in the scene.

Continuity: During the hockey scene between Van and Gwen, the radio on top of the goal changes angles between shots.

Factual error: At the beginning of the movie Van tells the viewers that it is the beginning of spring semester at Coolidge College and it is obvious that the college is somewhere up north near Massachusetts because in the scene where Van is giving the basketball team a pep talk one of the players asks Van if he invited the girls from Mount Holyoke (which is in Massachusetts)to their party. Yet throughout the entire movie everyone is dressed in shorts and tank tops like its summertime outside when in reality January up north near Massachusetts is FREEZING...

Audio problem: In the scene where Van goes to Gwen's house and meets her parents, Richard introduces Van to the doctors in the room. When he introduces Dr. Beaverman, the shot changes and Richard says "OB/GYN" and his mouth doesn't move. (Time)

Factual error: After Van unplugs the power from the phone, it rings one more time, remember, it's a cordless phone. (Time)

Factual error: In the scene where Van is in the court type room deciding if he can't stay, he drops outside the window and some photographers take pictures. They all use flash, which is ridiculous because the flash would have reflected off the glass and into the picture.

Factual error: Richard says that he goes to sleep at 11 before his exams, and he says he has almost three hours before then, but look out the window, it is still broad daylight. This is his first exam of the semester so it should be January or February and would not be light outside after 8 PM until April.
