I looked it up--today is in honor of Dr Tina Dupree, a 12-year employee of the second largest chicken restaurant in the US as Director of Community Relations and Training. She had a huge impact on the community and was a supporter of education, trying to raise standards. Through all of that work she became known as the Chicken Lady in her community, and eventually got to meet President Bush, who proclaimed November 4th as Chicken Lady Day (it's her birthday).
