Herbie Popnecker; Pincus Popnecker; Lyndon Johnson; Hubert Humphrey; Nelson Rockefeller; Charles de Gaulle; Queen Elizabeth II; Mrs. Popnecker
Herbie's father feels like a failure because he can't get Herbie to lose weight. Herbie enlists the help of President Johnson and Vice President Humphrey who call his father to Washington. Herbie's father can't understand why everyone seems to know Herbie: Governor Nelson Rockefeller, President Charles de Gaulle, and Queen Elizabeth. Johnson appoints Herbie's dad Ambassador to Hongadingia, with his first big job to end a war between the Hissians and the Pigturtles. Herbie becomes skinny after he is bit by a Hissian and his father becomes fat after he is bit by a Pigturtle.
