A billboard is bluntly telling Chicagoans that hot dogs cause "butt cancer" — and the hot dog industry is not amused.

The billboard is one of a series of ads being put up in major cities by the Physicians Committee for Responsible Medicine, or PCRM, urging people to stop eating hot dogs, which it says are a leading cause of colon and other cancers...Calling the ad "outrageous" and "inflammatory," [The National Hot Dog & Sausage Council] dismissed the PCRM as a "pseudo-medical animal rights group" bent on turning all Americans into vegans.

The PCRM does, in fact, suggest a vegetarian diet, which I guess makes them the mortal enemies of The National Hot Dog & Sausage Council.
