I Love You, Beth Cooper is a comedy novel written by former Simpsons writer Larry Doyle.
Upon graduation from Buffalo Grove High School, valedictorian Denis Cooverman states to the entire gymnasium that he's had a crush on cheerleader Beth Cooper for six years.
After the speech, it is revealed that Beth in fact has a boyfriend, an off duty army soldier named Kevin who threatens Denis.
After his declaration, Denis' mother and father leave him and Rich alone at the house for their party, which no one attends, as they are social outcasts.
Beth shows up in her tiny blue car with her friends Cammy and Treece (the group of three is known as "The Trinity") at Denis' house that evening.
Beth is meant to be a dream girl, but has glaring imperfections that shatter Denis' fantasy.
The group heads back to the high school where Beth, Cammy, and Treece show off their cheer leading act.
The group escapes in Beth's original car which Kevin used to drive down to the high school from the party.
Denis gives up his attempt at retrieval and returns to the car in only his "lucky" (meaning holey) underwear.
After beating up Denis a bit more they are confronted by Rich who has a rifle belonging to Treece's father.
Denis, fearing for his college admittance, jumps over and rescues Kevin revealing that he is a champion swimmer.
Fighting stereotypes of dumb teenagers Rich, Treece and Cammy had called the police.
[2] The film was largely faithful to the novel, but made a significant change by making Beth more outwardly responsive at the end to Denis' feelings for her.
