Here's Dr. Watson and his favorite ball in the world, which unfortunately got left at the MIL's house so it will be a while before we have it back. It's a Hartz DuraPlay ball...best squeaky ball I've ever bought, but terribly hard to find.
I also don't have any pictures of him actually playing with it, because anytime he's playing and I try to take a picture, he'll stop and pose for the camera. Not even joking.
