From the book:

My name is Jason Green, and I guess that I'm kind of a goofball. At least I was, until one of my pranks went wrong and I ended up having to get a job at the Whispering Canyon Country Club. That was when everything changed. After I became friends with Eugene, who absolutely loves golf, I started to play the game myself. To my surprise, I was actually pretty good at it! I'd never been good at anything besides making people laugh. Now I'm starting to think that maybe the cool kids aren't so cool after all. Maybe I'm not just the fat kid who's good for a laugh, maybe I'm a golfer...
