By way of a bet, Billy gets into the uncomfortable position of having to eat fifteen worms in fifteen days. Should he succeed, his friend Alan will have to pay him $50, enough to buy the minibike Billy pines for. 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 suppport of his friends and family, Billy munches away courageously. But there is many a slip twixt the worm and the lip, and the outcome of the bet is continually in doubt. Alan's not giving up $50 for any old worms. What will Billy do?
