Barry thought for a few moments and said, “I eat a special kind of fish.” “You eat a special kind of fish! What does that do?” “It makes my brain work better.” Barry said. “What kind of fish is it?” the reporter asked. “Give me fifty dollars and come back tomorrow. I’ll have some for you.”

The reporter gave Barry fifty dollars and returned the next day. “Have you got any special fish?” “Yes. Come into the house. It’s in the refrigerator.”
