Wardrobe malfunction. There's a term that didn't exist a few years ago.

After Binky tears his pants at school and accidentally reveals part of his underwear, Arthur starts having nightmares about forgetting to wear his pants. It's starting to affect him during the daytime, too. How can stop panicking about these bad dreams?

All kids love Arthur because of the television show (I liked it when my kids watched it), and all kids occasionally worry about something super-embarrassing happening to them. And, of course, occasionally those kinds of things happen in the classroom. This is a good book to read following an "unfortunate incident" at school or just during a discussion about how to deal with embarrassing situations.
