For whatever reason, Gary doesn't even mention this, but from reading Scott's post, I don't think I agree that it even got 1/5, let alone 3/5. The bell is not on the llama's tail in any of the examples, though it is very close to the tail in one. The robot is either looking over the cat or in an unrelated direction, never at the cat. None of those basketball pictures shows a robot farmer. The fact that one may be wearing a hat doesn't make it a farmer. He says he's being generous because he believes it would have gotten a farmer more easily than robot farmer, which may be true, but a human artist would easily be able to depict a robot farmer.

At least one other key to making a bet like this fair is that it needs to be arbitrated by a third party. He shouldn't get to decide himself if he won or not.
