Nurse: [to Mr. McNair] Knock, knock.
Janitor: [v.o.] Who's there? Nurse Mophead. Nurse Mophead, who? You have a mophead.
Nurse: Well, your new computer should be here tonight.
Janitor: [to Mr. McNair] She got out of here in a hurry, didn't she? I know what that's like, when people say the bare minimum to you. But with me it's usually, "Mop that floor. Clean that counter. Stop provoking that bear." Want me to keep you company? I don't mind. I'm just working on my own stuff anyway. I'm a bit of an inventor. I'm gonna show you my latest one: Pen straw. Perfect. Ahem! Except I don't like that cola. It tastes like ink.
