Dictionary.com defines "famous" as "having a widespread reputation, usually of a favorable nature; renowned; celebrated."
KFC, however, seems to have a slightly different definition: they proudly proclaim the merit of their "famous" bowls. I have not tried one of these, but it basically consists of mashed potatoes, corn, chicken, cheese, and gravy (or as my brother Josh says, everything that they were able to salvage from the trash). My problem with this whole thing is that they have the nerve to call them their "famous" bowls. Is KFC famous for their bowls? How often have you heard anyone say that they're going to KFC to pick up a bowl? When you thing of Kentucky Fried Chicken, what comes to mind? Call me crazy, but I think of...fried chicken.
You cannot arbitrarily decide that something is famous. Something is famous when it is well known. KFC is NOT known for their bowls! Hence, they do not have famous bowls! Oh, well...thanks for tuning in once again to the most famous (or is it infamous?) blog on the internets.
