I love this whole series of books. I keep a copy in the bathroom.
the conundrums from the book that aren't too over-the-top end up as journal topic in my Jr. High classroom.
My favorite: Would you rather appear as Yasir Arrafat in the mirror, or have Darth Vader's theme play every time you walk in a room. Things to consider: Shaving, putting on make-up, public restrooms.
