I don't know why people are applauding him for his behaviour, he's supposed to be an ambassador for Britain. He has the easiest life imaginable already, yet he still has to engage in stupid stunts (dressing like a Nazi), to emulate a rock star persona to try and distance himself from his oh so privileged upbringing.
Chip on shoulder? Do you have one?
Just because he was born into his position, doesn't mean he shouldn't have fun while he is young.
We've all got our kit off for the ladies before, why shouldn't he?
