"Can I try some of your cake, Robin?"
"No, it's poison."
"Can't I eat just a little?"
"Yes. Nothing bad would happen to you. But you would get sick."
"Maybe you could bake another cake, but this time without poison?"
"I'll do the recipe book, and you type stuff down."
Robin went to get the recipe book, and he never returned.
Sometime later, Robin did return. "I read all the recipe book. Here's your recipe book, Sir," he said. "It's another recipe book. I can't believe it."
Then Robin went away and was never heard from again.
