Whats the Smartest Thing Youve Seen Your Pet Do?

I used to have a little dog that was tiny as a puppy. He kept getting hurt because he would go right underfoot and people (and other dogs) couldn't see him. We would dote on him if he got hurt. Eventually he would act hurt every time he wasn't getting all the attention. Luckily by then we'd gotten used to his little presence and he got big enough to see with the naked eye.
