(Hank's bedroom at bedtime. It's dark. Mommy is hiding under Hank's covers, completely hidden. Superdad is escorting Hank to bed. Hank begins to climb in.)
Hank (giggling): Mommy, are you in my bed? Why are you hidden under all my covers? Were you trying to scare me?
Mommy: Yes, Hank, it's me. (Mommy pulls the covers off her head.) How did you know it was me and not a monster?
Hank (in a what-are-you,-stupid? tone of voice): Uh, Mommy, I knew it was you because a monster's feet would have been sticking out on the other end of the bed. You know, because they're bigger than you!
