Let's Stay Out of Crazy Town, Shall We?

When people try to tell me that animals don't have emotions, I proceed to go to Crazy Town in about...oh...0.8 seconds. It's photos like this one where the facial expression is so indicative of something so very real and raw (an expression that I unfortunately saw on the faces of many a traumatized client in my past work) that makes me want to shove it in the faces of any non-believer. Emotionless creatures? Are you kidding me?
