hold it. Aren't those communist propoganda posters in the background, like Yao was posing in front of on draft night? I knew it. Yao's a ploy to distribute photos of celebrities posing with pinko commie Presidents baring subliminal promotions of their sadistic campaigns to rob us of our precious bodily fluids.
Ok...it's perespective. The objects closest to the camera will appear larger.....on that note, Bush is tall, but he is not just a head shorter than Yao.
