Anal Leakage: Chiinese Billboard Assesses Sewage Problem

If sewage pipes and their smells somehow don't get enough notice by local communities, an ad like this might raise some eyebrows. Developed by a Chinese advertising company for use in Shenzhen, in Guangdong province, the posters drive home the message that pollution is poopy (while reminding people where some of that pollution originally comes from). In the world's ecological ground zero -- and in a country not known for racy billboards -- shock value can go a long way.
