Do You Really Want to Know How It Ends?

The Ending - Van Wilder is expelled from Coolidge College for allowing kids to drink at one of his campus parties.  Van was actually set up by Richard Bagg (piece that one together on your own) and his fraternity brothers.  Van appeals the expulsion and convinces the review board to let let him take the final exams in the six classes he needs to graduate.  With the help of just about everyone on campus, Van passes his classes and graduates after seven years.  Gwen gives Richard a power shake filled with Ex-Lax just before Richard takes him medical entrance exam.  Richard can't finish the test because the crap that's building up in his body, then he's unable to control his bowels in front of a few influential medical school alumni.  Gwen writes a favorable story about Van in the school paper and sends a copy to Van's father.  At the graduation party, Taj hooks up with an Indian girl from his part of the country, Van and his father reconcile, and Van hooks up with Gwen.

The Ending - Charlie and Wesley arrive at Betty's apartment as Betty is packing up to return to Kansas. They check her "Buick" and find the drugs they were after in the beginning of the film.  The two of them knock on her door and her roommate answers. They pull their guns on her as Betty walks in. There's a knock on the door, and this time, it's the local policeman and the newspaper reporter from her home town. Charlie takes Betty into the bedroom while Wesley takes Roza, the reporter and the cop hostage in the living room.

In the bedroom, Charlie explains to Betty how he's been thinking about her ever since they left Kansas and how he thought that Betty was the perfect girl for him. Meanwhile, the cop manages to pull his gun and, as the two scuffle, kill Wesley. Charlie tries to get away but Betty won't give him the gun so he just walks out the bedroom door and is shot and killed.  The press arrive and Betty is a hero. The producer of the show convinces McCord to offer her another part on the show (just for ratings). Betty joins the cast is a big hit.  As the credits are about to roll, we're told that Betty starred on the show for about three months and with the money she made, went to medical school to learn to become a nurse and also took a trip to Europe.  The final scene shows her throwing coins into a fountain in Italy.
