Chase as Zack's personal wind-up toy

Prior to this video, Chase was making Zack laugh by drumming (with two pencils) all around the living room. Of course, by the time I got the camera out, Chase didn't want to make him laugh again, as he "had enough". But, Chase is still a ham for the camera. And, Zack still loves smiling at his brother, his own personal wind-up toy.
