KFC TV Commercial, 'Mashed Potatoes and Gravy v. Mac and Cheese'

This commercial shows a grandfather and his grandson arguing over the side for their KFC meal. The grandfather wants mashed potatoes and gravy, but the grandson argues that it's his turn to choose and he wants mac and cheese. They begin to wrestle and the rest of the family walks in carrying KFC's meal where you can get two sides extra. The family, enjoying the wrestling match, neglects to tell them.
