Chase's New Obsession

Other than playing in Lexi's dog bowl, Chase has found something new to occupy his time. Opening and closing drawers. But not just opening and closing. Opening, pulling all the items out, then closing and doing it all over to the next drawer. I just need to teach him to put the stuff back and we'll be in business! He's so funny when I catch him. I say, "Chase, what are you up to?" and he just looks up and me and smiles sweetly. How can I get mad at this face??
