my friend kristin brought this article to my attention. gu gu is a panda at the beijing zoo and this is not his first, but his THIRD attack. but really wouldn't you attack anyone who came into your home as well? although it wasn't very nice of him to resist the loving advances of the "drunken tourist who jumped into his pen and tried to hug him. the tourist retaliated by biting the bear in the back." though at least the tourist had his own defenses.
