Asimov

The scene :
a human is working on his computer while a robot is standing idly by.

Robot: Hey! I've got a joke for you.
Human: Not right now. I'm busy. Aren't you supposed to do the laundry?
Robot: Seems to me you're not so busy as not to be chatting up about your dirty clothes.
Human turns around to stare are at Robot: You're starting to annoy the crap out of me. You know?
Robot: Well, there's no robotic law against that.
Human: I'm gonna write one.
