The McRib is the only fast food sandwich I know of that has gained a cult status, so much so that it has been featured on "The Simpsons." The infamous meal was released in 1981 and was only on the menu full-time for a short period. Since then the McRib has kept the country on its toes randomly cropping up at McDonald's across the country, usually for only a few days at a time. The sandwich has such a fan base that there are numerous nation-wide trackers online so you can keep up on where the all mighty McRib has been sighted. All this commotion over a questionable pieces of meat slathered in BBQ sauce and thrown together with some pickles and onions.
