The other night when I went to a Relief Society meeting, Matt taught Dean and Walter the "tree chopping" game. He would "chop" their legs and push them backwards onto the bed. They LOVED it and begged me to play it with them the next couple of days. Dean got to the point where he was chopping himself, but the funniest part to me was how he'd say, "chomp, chomp, chomp." Here's a video of it.
