Wild animals are nothing to play with. Even in a zoo or "controlled setting" it is important to remember they are still wild animals with very real instincts and behaviors, so making sure you don't senselessly put yourself in harm's way is paramount to your safety.

In this clip, two guys are getting a picture taken with a tiger who is perched on a platform with a small chain or leash around its neck (like that is going to stop it). The tiger lets out a roar and these two decide it's time to get the heck out of there. They probably need a change of underwear after that.
