Mrs. B: Eliza, will you please pick up that little square of paper off the floor?

Eliza: But it's not mine.

Mrs. B: Yes it is. It fell out of the little hole at the front of your desk.

Eliza: There's a little hole at the front of my desk?

Mrs. B: Yes. All the desks have them.

(The entire class begins feeling around under their desks. There are lots of "ohs!" as they discover them.)

Justin: I wonder why they put those there?

Joey: So your desk can poop.
