Senior Trip is one of the last few funny movies in the National Lampoon series before they gave way to ultra cheap movies, horribly unoriginal scripts, and poor comedy.

Welcome to Fairmount High, the educational institution of a braindead student body overseen by the idiotic Principal Moss (Matt Frewer) (ala Principal Rooney, only funnier). After the amazingly funny team of D'Agastino and Reggie's plans for a senior class party at the prinicpal's house lands them and some of their buddies in detention (I don't know why the selected few were the only ones to get busted). Only shielding themselves from a harsh punishment by reasoning that somehow the school system is responsible for their troublemaking ways, Principal Moss gives them an assignment: write a letter to the government citing their grievances for the poor education system.

This is something Moss will regret later as the President receives the letter. He calls up the Senator who's state Fairmount High is in and tells them to send the class up to Washington because these kids are going to help sponsor his education reform bill. The last thing anyone in their right mind would do is stick these burnout party kids on a bus (for some Van-damage!) for a couple days. And with Tommy Chong, as "Red" (named for his immunity to horse tranquilizer as he demonstrates later), as the bus driver, all hell breaks loose! The President is in for a big surprise, and that's exactly what Senator Lerner wants. Once he meets the group of misfits, especially Miosky (Eric Edwards) the silent bonehead chow hound, he knows that their appearance before the committee will pull support from the President's bill, and permit him to introduce his own education reform bill.

Meanwhile, Dag's slow talking pothead friend, Reggie, is being chased by a psychotic Trekkie crossing guard, Travis (Kevin McDonald), who Reggie earlier insulted, adding a hilarious subplot of the deranged wacko dressed in the Captain's uniform and carrying a blow-up doll who just won't seem to leave Reggie alone.

The movie, albeit an incredibly stupid plot, it is outrageously funny, watching Dags, Reggie, and the gang foil Principal Moss's plan to keep these misfits from causing too much trouble. Besides Dag's, the arsonist, and Reggie, his spaced out friend, there's Virus, the horny Audio/Visual geek; Wanda, Reggie's equally spaced out girlfriend;, Lisa, the brain; Herbert, the guy who is in perpetual mourning; Meg, the lesbian; Steve, the preppie jerk who gets his just deserts; Miosky; and Carla, the nymphomaniac.

These kids do everything from locking their principal in a flooding convenient store bathroom to steal beer, to drugging their principal and chaperone, a timid math teacher, to throwing a rad party in a crude man's huge hotel room. It is one of the better teen comedies you'll find in the late 90s and one of the last few National Lampoon movies. I recommend checking it out.
