PAUL: Why is there a dog brush in our bathroom?
ME: It's for dogs AND cats.
PAUL: Why is there a pet brush in our bathroom?
ME: I couldn't find either of my brushes, so I used it. It's brand new. It's never been used on an animal.
PAUL: So, instead of using my brush you used the dogs'?
ME: Your brush does weird things to my hair. And it's the dog AND cat brush.
PAUL: And the pet brush doesn't do weird things to your hair?
ME: No. It works pretty well.
PAUL: Of course it does. That makes perfect sense.
