The phone

Duke has a very active social life. He loves yappy hour at the dog park down the street. Yesterday he managed to take off his collar. I looked everywhere. As a result I lost my phone. it was only after filing the request for a new phone I discovered it under the bed where I had searched for the collar. My sister Linda suggested I have underestimated Duke's intelligence. "Who has lost his cellphone?" He also got himself on the swivel office chair. I would love to have that video.
