Malcolm: [wakes up] My back's killing me. What happened?
Dewey: Malcolm, you're awake. We were worried about you for a while.
Malcolm: What happened to the new mattress?
Dewey: What are you talking about?
Malcolm: The mattress! I know there was a mattress.
Dewey: Maybe it was a dream.
Malcolm: It wasn't a dream! The mattress was perfect and white, and it felt like a cloud! It fell out of the sky, and it made me happy!
Dewey: Was it just a bed, or was there a beanstalk, too?
Malcolm: [sighs] Maybe it was a dream.
Dewey: You were happy, Malcolm. Of course it was a dream.
