Cody:  Mrs. B, what are you going to be for Halloween?

Mrs. B:  I'm going to be a flower.  What are you going to be?

Cody:  I'm going to be a teacher-eating monster.

Mrs. B:  Well, I guess it's a good thing I'll be dressed as a flower.

Cody:  Oh, I'll be the kind of monster that can tell if you're in disguise.
