When I did E3 with the Wargamer crew back in 2003, the game Blitzkrieg was being pimped. The developer had imposing actors dressed in full Wehrmacht uniforms, sporting (fake) MP-40s. Something like that, I totally get (it certainly drew attention, which is what they wanted). Just being a random dude wanting to dress like that...well, it reminds me of the Halloween episode of South Park where Cartman dressed up like Hitler. I don't dare search for that clip here at work.
