I love stupid dog tricks on David Letterman. While the dogs usually perform pretty cute stuff, I always like the way Dave seems a bit afraid and skeptical of the four-legged performers. On Thursday night, a beautiful French Briard named Norman (love that name), broke the ice with Dave by riding a scooter better than most people can. Seriously this dog cracked me up. Maybe it was the long beautiful coat, his expressive face or the fact that his feet were as big as mine, but I really thought it looked like a kid dressed up as a Muppet riding the darn thing.
