Doritos in Japan

I was reading a blog post about falling domestic car sales in Japan, but what really caught my eye was the accompanying photo (go on, have a look). I'm not sure what the two guys on the packet of Doritos are supposed to be doing, but perhaps it's an aid to digestion. It reminded me a bit of how, when tea was first brought to England, people didn't know what to do with it, and some people just boiled it up, threw away the liquid, and ate the soggy tea leaves. I'm starting to wonder what people actually do with Doritos in strange corners of the world.
