While sitting my car, spotted a power walker, out for his morning exercise. In tow, he had a golden Labrador, on a lead. The walker came to an abrupt stop, when his dog spotted some nice fresh green grass and started rolling and pushing itself along the grass on its back. Didnt matter how much the walker yelled or yanked the lead, that dog wasnt going anywhere, until it had its fix. Ahhhh, its the little things
