A fifty dollar bet to eat fifteen worms in fifteen days? It seems like a no-brainer to Billy, but he finds it's easier said than done especially when Alan the bully stands between him and the prize. By way of a bet, Billy gets into the uncomfortable position of having to eat fifteen worms. The worms are readily supplied by his opponent, and Billy has a free choice of condiments, from peanut butter to horseradish. With his wavering courage bolstered by the moral support of his friends and family, Billy munches away bravely, but there is many a slip twixt the worm and the lip, and the outcome of the bet is continually in doubt. Young readers will share author Thomas Rockwell's delight in the incredible pranks of his characters. His fast-paced, original story is written with a genuine understanding of the kind of humor children love. Lively drawings by Emily McCully help make this a bok with irresistable reader appeal.
