There was a monkey sitting in a banana tree. He was very hungry. He knew that somewhere in the tree there was a magic banana, and that once he ate that banana, he wouldn't be hungry anymore.
He ate one banana. That wasn't it. He was still hungry. He ate another banana. That wasn't it either. He was still hungry.
Finally, after he ate his tenth banana, he wasn't hungry anymore. "I knew I'd find it," he said. "It's too bad that I didn't eat that one first. I wouldn't have to waste all those other bananas."
