Crush: The Theory, Practice and Destructive Properties of Love

Every time Kevin Spencer sees Tina Zabinski, the Most Beautiful Girl in the World, he's in danger of tripping, falling, and making a fool of himself. He can hardly say a word to her. But Kev knows he'd be the perfect boyfriend for Tina. He's not bragging. Just pointing out the obvious.

Kev decides to take a scientific approach to getting a date with Tina. After all, love is based on chemistry. When new kid Cash Devine zeroes in on Tina, Kevin hustles to find the formula that will make her forget all about Cash.
In Gary Paulsen's companion to Liar, Liar and Flat Broke, Kevin's experiments in true love are truly hilarious.
