Keith and Amanda go out on their date in a limo driven by Watts (the tomboy). They hit it off and Keith gives Amanda diamond earrings. They go to Hardy's party and are confronted by him and his friends. Keith tries to fight Hardy and is pulled back by his friends. Just as they are going to beat Keith up, the tough guys of the school (who Keith made friends with in detention) show up and save him. Amanda slaps Hardy and she and Keith leave together. Amanda then tells Keith she would rather be on her own for a while. Amanda gives Keith back the earrings and leaves. Keith realises he is in love with Watts and runs after her and gives her the earrings and they wind up together.

Duncan: We're gonna bring this party up to a nice respectable level. Don't worry, we're not gonna hurt anyone. We're not even gonna touch 'em. We're just gonna make 'em cry a little, just by lookin' at 'em.
