Everyone knows that the custodian is one of the most important people of the school and he is somewhat of a mystery.  He’s the only one who knows where all the secret places are hidden.  In this elementary school, Fester Smudge (Uncle Fester?) is the custodian, and apparently he has talent for disaster.  Kids have the best imagination when it comes to what adults do, and this is a great example of that imagination.  After fantasies of flood, dragons, and caves, Mr. Smudge is actually a pretty nice guy.
