Hal: Okay, Dewey, there's one bat left, and it's in your mother's room. Now, this one is the tricky bat, the one who has eluded all the other traps. What was it you named him?
Dewey: Tricky.
Hal: Right. Well, now we have a very good trap, but someone has to lure Tricky into it, and that someone is you.
Dewey: Why me?
Hal: Because... you have the shortest hair. You see, if he lands on your head, he'll just bite once and fly away, but if he lands on your brother's or my head, he'll get caught in our hair and bite us and bite us until we are dead. Do you understand that?
Dewey: Yes.
Hal: Good. Now... I want you to go in that room and poke him with this stick until that bat chases you. Good luck.
