1) Baby Jesus at Occupy Bethlehem Sweater
It used to be the hideous Christmas sweater was only offensive to one's sense of fashion. These sweaters go way beyond tacky design to offend one's sense of moral decency and general notion of how erotic or politically charged a sweater ensemble can get while still being considered "Christmas-y." Wear one to the next family gathering you fully intend to be kicked out of midway through your sixth egg nog.
