Pig's head anyone?

This guy on the bike was really sweet. He saw me taking pictures of the brothels and was fascinated. I greeted him in a Universal male way -- gyrating body movements etc -- which he found hilarious and then followed me round for the next 20 mins chattering away in Mandarin. I treated him to the four Mandarin words I know: 'Hello'; 'Thank You' and 'Beer'. More hilarity. Then he insisted I take his photo. It was not until that point that I noticed he had a pig's head on his trailer -- sans face. insane.
