Visitors at the San Diego Zoo were nervous when a stray dog somehow ended up in the gorilla exhibit. Once the gorillas notice the dog, they begin to move towards it. No one is sure what they're going to do. In the end, the dog was rescued by workers and unharmed. He's currently at the human society where they've named him Mighty Joe Young. They will determine if he has owners or if he'll be on the hunt for a new family. Not your average day at the zoo.
