It's Show-and-Tell time in Mrs. Krupp's class, and Billy just can't wait for his turn! Today the class is discussing what they want to be when they grow up, and our exuberant eight-year-old hero is bursting to tell everyone about his future career plans. In dazzling wordplay and delicious rhymes, Billy regales his patient teacher and amazed classmates with tales of the variety of careers he wants to pursue—each more outlandish and wildly imaginative than the last!
