A yearly contest in my hometown of San Diego is the Ugly Dog Contest, we actually held one of the first ugly dog contests in the world. This years winner was little Chomper, a boxer mix who can't put her toungue in her mouth. A video of the event can be found here. It's very cute to see happy Chomper's toungue wagging about throughout the event.
The event actually is great for our city's animal shelters, as all proceds are donated to them. The San Diego Kiwanis put the whole thing together and other catagories include best St. Patrick's Day costume, Best outfit, cutest dog and best mutt.

Some of those dogs weren't even ugly though. Guess people think just b/c it's wrinkled or hairless, it's ugly.
