A: Where's the pencil sharpener?
B: Which one?
A: Any one. I need to sharpen this pencil.

A: I already looked there.
B: Did you look in the desk drawer?
A: Yes, I looked there, too.
B: Don't we have about five sharpeners?
A: Yes, but they seem to have legs.
B: Tomorrow I'm going to buy an electric sharpener.
A: Get one with the rubber suction cups on the bottom.
B: Yes. That way it will stay where I put it.
