When my son was about 3, I used to give him Ready-Brek for breakfast. Then he suddenly started refusing to eat it, and wouldn't tell me why. Finally, after a week or so of refusing and my asking "Why?" he finally burst into tears and said, "I don't want that little man to come!" It all clicked--Ready Brek had started running a TV commercial that showed a smiling little man emerging from the steam of the bowl, and my little boy obviously thought he was real, and would appear over every bowl of Ready Brek.
