If the obvious photoshop job didn't convince people that it's fake, the outlandish nature of the interview should. Seriously, Yamauchi's a pretty strange character, and he's done some ... "interesting" things in his time but I hardly doubt he'd conduct himself in that manner throughout an ENTIRE interview. I got about 5 questions in before my bullshit alarm went off and I realized the person behind this was a grade 8 student writing a fake interview for creative writing class. Fun read, though!
