During the beginning of the movie, I was wondering why this was supposed to be so funny. I'm not into crude teenage boy humor where they talk about sex and girls in graphic detail that teenage girls would be horrified to be mentioned. However, once the plotline involving the fake id and the party started, the vulgarity was put aside for the most part and I actually thought the movie was funny.
Seth and Evan, best friends forever, are about to graduate from high school and have gotten into different colleges. When Seth's partner doesn't show up for their home economics class, he is paired with Jules, a girl he is interested in, who invites him to a party she is having that night. Seth and Evan haven't been invited to a single party during high school. They're excited to go, especially when Evan finds out Becca, the girl he has a crush on, will be at the party.
When their friend Fogell says he's getting a fake id, Seth tells Jules that he has a fake id. When she asks him to pick up the alcohol for the party, he agrees. The story really gets going once Seth, Evan, and Fogell meet up outside the liquor store. From there it's chaos and the goal of providing alcohol as well as getting to the party are in jeopardy.
If you can get past the crude beginning and overlook the weak ending, it's got some good laughs and is worth seeing.
