You know those videos you occassionally see on Letterman or Leno where a small animal (like a squirrel or a dog) gets on a skateboard or a surfboard and rides around on it for a little while? Well, someone made a full-fledged "sport" out of this. Each May a bunch of dog owners gather in San Diego, plop their pups on surfboards and throw them into the ocean. Then, someone judges each dog's performance on confidence level, length of ride and overall ability to "grip it and rip it." Yes, you read that right. How you can grip, and then rip, a gnarly wave without an opposable thumb must be something you have to see in person to understand.
