Not only has this become a billboard, but it's become a controversial piece of news!
The Physicians Committee for Responsible Medicine erected this billboard in Chicago. Because saying "butt cancer" is not hilarious and totally counts as "responsible medicine."
They put it up to help people in the hot-dog capital reduce their colorectal cancer risk.
