Jason: Your brain needs a break
Eric: No, my brain needs air. There's not enough air in here... but there's plenty outside! (dashes for the door) (inhales deeply) Ah; good ol' H-2-O.
Jason: If your score drops any lower, you won't even get into Clown College.
Eric: ...is that a four-year school?
Shawn: If I wanna clip my toenails at the dinner table, I don't appreciate all the dirty looks.
Cory: We were just covering our food.
Jason: You're score is...190.
Eric: That's impossible. You get 200 points just for signing your name. (looks at test) Two "t"s in Matthews!
Shawn: Facial hair sprouts early in my family, especially on my mom's side.
Cory: Come on, Shawn. You've lived here three weeks and you've been in the bathroom two and a half of them.
Mr. Feeny: Care to take a guess what secret #3 is?
Eric: You're Satan?
Turner: Why can't you be this sharp in my class?
Shawn: Math's not my best subject.
Turner: I'm your English teacher.
Shawn: Then why you teaching math?!
Turner: Are you kidding me?!
Eric: Hey, Hunter what the heck do you think you're doing?
Shawn: Uh, cleaning out my ears.
Eric: Yeah, with Towely, my lucky towel? Are you insane?
Shawn: One of us is.
