Tyson the Skate Boarding Dog

This Video from Youtube has been online for 2 years now and has over a million hits, presumably because everyone wants to see the last 3 minutes of it, which features a skateboarding dog named Tyson.

Also on offer are some funny kittens, a hopping penguin, a polar bear (can't quite figure out if he's really tired or just lost the use of his front arms...)
