Jonathan Cleaned Up -- Then He Heard a Sound: or Blackberry Subway Jam

This book has all the classic Munsch traits - an exceedingly improbable situation (subways keep opening up into Jonathan's apartment, making progressively greater and greater messes), useless adults (his mother blames HIM for the impossible mess, and at city hall he's told the routes can't be changed), and a silly solution (he bribes the man who makes the maps to move the station to the mayor's office. LOL!)

It's great. Silly, fun, over-the-top, and no pretense at a moral. Plus, bonus - trains! If you're a fan of Munsch, you know you want this. ( )
