The question you always have to ask when seeing a photo like that...
is, "Is it real, or was it PhotoShopped?"
Graphics manipulation is so easy and common that it's always a good idea to be skeptical. It may well be real (and if so, the guy's a Bowser), but we may never know for sure.
Makes me wonder about what will be the legal standards for admitting photos as evidence. How do you prove a photo is legitimate?
