21 - 5: The Devil Wears Nada

In an effort to raise money for charity, Marge and "Philanthro-Chicks" decide to pose for a calendar. At the photo studio, Marge is a bit reluctant to reveal any skin, but the photographer loosens her up with wine and before long, Marge and her pin-up poses are the talk of Springfield. Blackboard: 'I do not have the hots for my mom'.
