In 2007, Tillman the bulldog amazed the world with his video of him riding a skateboard around a park, just as naturally as you please. Apparently the dog is still refining his moves, via Tony Hawk's video game. (Obviously, he's not playing the game, but he's definitely into it.) More videos of Tillman snowboarding, surfing, and of course, skateboarding can be found here. Tillman's website.
