When Calvin and Hobbes were little they used to play with each other on either side of the bathroom door. One day I came home to a very concerned Calvin at the door. He immediately ran to the bathroom door with a very "HURRY UP AND SEE" look and found the door shut. No doubt Hobbie who outweighs Calvin by quite a bit pushed the door shut while playing on the inside. Don't know how long he was in there but I think he got the better end of the deal since the litter box was in the bathroom and poor Calvin had his legs crossed for who knows how long?? Of course Calvin was on the food and water side of the door and I'm sure Hobbie would have traded in a NY minute!
