I once spent a couple hours with him in a little SF comedy club. I was just 3 feet from the stage and tossed him ideas that he improvised on. Such a quick mind, very funny, and very creative.
He's getting stocky. When I found him three years ago, he was terribly thin. He still enjoys eating garbage along the road, but we now supplement that with Purina Dog Chow.
He's been good about coming back after his morning run. His tail is very expressive, and not always arced forward like that.
