I've trained my dog to clean up the yard

I don't actually have a photo of him cleaning up the yard, so this bathtub shot will have to do. Anyway, Copilot and I have a new routine. When I take him out back to play fetch, he's required to bring a stick (the yard is, or should I say was, littered with sticks) before I'll throw his tennis-ball-with-a-raccoon-tail-attached for him. I'm very proud of this. I'd like to think that it puts me in B.F. Skinner territory, but I'd probably be overestimating my positive reinforcement skills.

I do have to say, though, the yard is looking better these days.
