Road Trip has a simple and pretty futile storyline. There's this guy, Josh who's studying at Ithaca, New York. He has a girlfriend, Tiffany, who studying at Austin, Texas. They have been together since they were kids, and have managed to remain faithful to each other. There's this other girl, Beth who likes Josh, and although Josh likes her too, he's committed to Tiffany, so he and Beth are just friends. A misunderstanding leads Josh to believe that Tiffany has dumped him, and one night, he sleeps with Beth, who, just for fun, records the whole thing on a camcorder. Then, in another misunderstanding, a friend mails the videotape to Tiffany. At the same time that Josh finds out that Tiffany has not dumped him and is just out of town for a few days, he also finds out about the videotape, and he decides to race to Austin and try to recover the tape before Tiffany sees it. This sets the scene for the road trip itself. The rest of the film is about Josh and a few friends trying to get to Austin as quickly as possible by car, because they can't afford a plane ticket.
The two funniest characters in the film are a guy called Barry who's basically half insane, and Kyle, the stereotypical unpopular geeky loner type who just happens to own a car, and so suddenly becomes everyone's best friend. Barry, who stays behind at school, becomes obsessed with feeding mice to a pet snake, and in one unbelievable scene he actually puts a white mouse in his mouth. Kyle, who of course lacks self esteem, finds some during the trip, and in standard fashion we learn that his father is a tyrant and Kyle has to learn to stand up for himself, etc, etc.
It's only now that I realise how bad this film really is. But it's saved by the fact that its utter stupidity makes it really funny. Well, at least I was laughing, anyway.
