My wife and I had just finished tucking our five young ones into bed one evening when we heard sobbing coming from three- year-old Billy's room. Rushing to his side, we found him crying hysterically. He had accidentally swallowed a penny and was sure he was going to die. No amount of talking could change his mind. Desperate to calm him, my wife palmed a penny that she happened to have in her pocket and pretended to pull it from Billy's ear. Billy was delighted. In a flash, he snatched it from my wife's hand, swallowed it and demanded cheerfully, "Do it again, mum!"
