Bucknell University students had a bake sale to protest affirmative action. They sold the goods for different prices based on race to make a point. When the Dean found out the protest wasn't in favor of affirmative action, he shut the event down on a technicality. Even though the students had the approved form filed three weeks in advance, the Dean put a stop to the sale because they were charging less than the $2 listed on the form.
