J.D.: Going on vacation?
Janitor: I get it - 'cause I'm a janitor, so, when I pack for a vacation, I just pack cleaning supplies. That's funny!
J.D.: I thought so.
Janitor: Actually, I'm going to speak at my son's career day.
J.D.: About... being a janitor?
Janitor: What do you think, there aren't kids out there that want to grow up to make the world sparkle?
