KFC's mashed potatoes still rock... actually... the potatoes really don't so much, the gravy does though.
Now let me tell you of a story, a KFC in north Houston was the local distribution point for Cocaine. Almost everyone that worked there was in on the distribution, or the usage of said drugs. The code word for the regulars who were there for their stuff, was "Extra Biscuits". Now the person working the counter one day must have come into work under the influence, because a Harris County Deputy comes into the store, in full uniform, and makes an order, and innocently asks for extra biscuits. The counter worker obligingly puts the coke in the bag. The officer stopped at the condiments counter before leaving, and spotted the package. He promptly arrested the entire staff.
