The Sid Fleishman Humor Award is given annually to the best humor book published in the previous year. This year the winner is The Fourth Stall by Chris Rylander. Mac will fix your problems, whatever they are. With the help of his BFF and fellow Cubs fan Vince, he runs his 'business' out of the fourth stall of the boys room. On a new assignment to protect a third grader from a bully things go hysterically awry.
