You're sitting around the dinner table. It's Christmas Day. Most of your family is there, along with a few friends. You've all just finished eating. You're talking about your Aunt Carla, who isn't there. You know which aunt. The one with the lisp. Everyone around the table is imitating her, and Aunt Carla walks in and asks, What'th tho funny? Then your niece shoots milk out of her nose and your smelly uncle pees in his pants. That'th thith book. Read it. You might pee yourself.
