J.D.: [gasps] Why do you have to jump out and scare me all the time?
Janitor: I don't jump out and scare you. I follow you around all day. I only got about an hour-and-a-half worth of work around here, and the rest of the time, I track you, like an animal.
J.D.: You're kidding, right?
Janitor: [chuckles] I don't know. Am I?
