Turk: Where the hell is Carla? Man, we're gonna miss the previews.
J.D.: Hey, you're black, right?
Turk: Here we go.
J.D.: I hate that stereotype that all black people yell at movie screens. You know, like you go see some horror flick and you'd be yelling, "Don't go in there, girl! He behind the door!" You know? It's like, it's offensive.
Turk: You wish you were allowed to yell at the screen, don't ya?
J.D.: Why does she go in there? I mean, he's behind the door!

J.D.: Going on vacation?
Janitor: I get it, 'cause I'm a janitor, so when I pack for vacation I just pack cleaning supplies. That's funny.

Janitor: Actually, I'm going to speak at my son's career day.
J.D.: About being a janitor?
Janitor: Well, you think there aren't kids out there that wanna grow up to make the world sparkle?
