Yes, I know: there is a "Hot Dogs Cause Butt Cancer" billboard greeting drivers on the Eisenhower. The message, which shows a cartoon man holding a hot dog while looking at his rear, comes from the very official sounding Physicians Committee for Responsible Medicine, and is just one of many signs the group has released around the country. Considering how much all of us at Serious Eats: Chicago love our hot dogs, this one seems especially intended to infuriate us. So we're going to stay cool. Plus, Grub Street Chicago already published an excellent analysis of the whole stunt, which you should definitely check out.
But what do you think? Does this add make you want to give up the encased meat, or does this just make you want to go out and order a fully loaded Chicago dog for dinner? May I suggest a few dozen places that serve excellent natural casing hot dogs? Oh, and I do hope that this is last time "butt" is mentioned on this site for awhile now.
