Every year a bunch of neo-Nazis march through the German village of Wunsiedel to the former gravesite of Adolf Hitler's deputy Rudolf Hess.
This year, the town decided to do something about their Nazi problem by letting them continue to march, while at the same time, collecting money for an anti-Nazi group called EXIT-Germany.
For every meter they marched, local businesses agreed to donate money to the organization, and by the end of the day, they had raised about $12,500. The Nazis didn't know about the fundraiser until they saw signs along the route encouraging them and reporting on their progress.
You can watch the video above produced by the group who organized the event, "Right-wing Extremists Against Right-wing Extremists."
