Kelso: I gotta study. They're really riding me down at the Police Academy, and I don't know why.
Hyde: I know why. It's fun.
Kelso: They even chose me last to work on the CPR dummy, so everybody's spit was all over it. You know, even Johnson's spit, and he's got a monster cold sore.
Roy: I know why they're doing that. I bet you're the stooge.
Kelso: What?
Roy: Every year, the Police Academy lets one guy in they know will fail out. They use him to scare the other cadets. I know 'cause my brother was a stooge. All right, fine, it was me.
