"I wish that in a few minutes Jon will get the stone back, but first, he'll accidentally wish himself to have a pussy, and second, he'll accidentally wish he never found the stone, so it'll be found by me instead. I wish that when this happens me and Jason don't forget anything."
"What, really?" asked Jason.
"Yeah, really. I was only saying it as an expression, but then I figured out it would be a great idea if Jon really did wish he never found the stone."
"You could just wish that yourself," said Jason.
"Yeah, but that way isn't as much fun."
A second later the stone disappeared. Jon looked down and picked up the rock. "Oh, there it is!" he said.
