Janitor: That's very wasteful. Must you wash your hands so often?
Carla: I just changed an 80 year-old man's diaper and I'm about to eat a muffin, so if you don't mind, I'm gonna wash away.
Ted: Ooh, I do not wanna see this.
Carla: See what?
Janitor: He expects me to make you drink my mop water. But my bucket's all the way down the stairs, so I'll let you off the hook if you promise never to tell Ted. Yes?
Carla: No.
Janitor: I'm gonna take that as "yes". That's it! Drink it down, baby. All the suds, too! You've learned a lesson.
