FOOL: (looking at the diaper pail) I wonder why the thing doesn't close?
ME: (thinking he is talking about the nightstand) Because it's stuffed full of magazines and books.
FOOL: No, it's not.
ME: It is. They're probably stuck in the hinge or something.
FOOL: It stopped working when I took the insert out.
ME: It doesn't have an insert.
FOOL: Yes, it does.
ME: What are you talking about?
