Ryan is all about balls lately, and has recently begun to call lots of DIFFERENT things "balls". That wouldnt be a big deal, except for the fact that he also associates the word "ball" with throwing. So if he calls it a ball ... he's gonna throw it.
Note: Yes, he is throwing ornaments from the tree. Luckily they are the shatterproof kind. And if you are wondering about the pink thing he is carrying around (in addition to the two ornaments) ... its a dog collar, of course!
