Dude. DUDE. WTF?
This seems to be some kind of crocodile-watching, educational tour, but how is this guy still alive? If we were the crocodile, we'd enjoy the appetizer so much we'd feel free to move right on to the main course.
Clearly, there's more going on here than we understand, but if we had to guess, we'd going to go with crocodile depression. We've been too down to eat before, too, Crocy.
But, seriously, dude? What are you thinking? The face of the kid who is taping pretty much says it all.
