When there's a miscommunication between man and dog over who is going to grab which part of a toy, the man usually wins on principle just due to species superiority. The dog however, usually wins on points, specifically the points on his sharp canine teeth.
Murphy and I had such a miscommunication a few hours ago, with both of us grabbing the same part of one of his flat basketballs. I know that he meant no harm, but I'd be willing to bet that his teeth don't hurt anything like my thumb does right about now.
So if you'll excuse me, I'm going to go watch my thumb nail turn blacker.
