People, there is an errant penis out there, which we are finding out about via Craigslist (natch). A poster says: "Lost penis sculpture. Last seen on February 4th, 2010 around 1 a.m. on display during the art show BYOA at X Initiative located on 548 W 22nd St. The art piece is a life size realistic sculpture of the artist's penis and testicles made out of resin and beard hair. There were four Mark Billy penises on display but only one peach colored one went missing." Well, we know where he can get another one on the cheap. You can get a closer look at the missing sculpture, and its friends, here. Meanwhile, the artist is so distraught he hasn't even Twittered about it.
