Somewhere I have a picture of my big guy trying to squeeze thru the hand hole for a 12 pack of Diet Pepsi...the box ones? ANd he still tries to put his 20pound body into a shoe box. It is just so much fun to watch him approach from all different angles. There is so much determination there! FInally he figures out that he should just tip it on it's side and hide his head...that is usually when he gives up....
