Okay - I have a soft spot for things that are so ugly they are beautiful.
Take the bulldog for example. Who could not love a face like that.
We had a bull dog when I was growing up -- he looked much like the above pup. His owner left him at the dog pound, apparently to "teach him a lesson". My Grandpa worked at the pound and when on the third day at 5:00 the owner didn't show up he claimed Sir Percival for us. When the agitated owner got to the pound at 5:30 looking for his "No good dog", he was informed that it was too late. Technically it was and he never need know that the pup he abandoned went on to live a long life with a loving family.
