How to Get the 'Monster Dance' Achievement in Assassin's Creed: Revelations

This one goes perfectly with the 'Mosh Pit' achievement I posted about earlier today. To get the 'Monster Dance' achievement in Assassin's Creed: Revelations, you have to get a guard to incapacitate three civilians.

As demonstrated by PowerPyx, the best way to do this is to throw money for the civilians to run toward, while the guard flails around. Doing this will earn you a bronze trophy on PlayStation 3, or 20G on Xbox 360.
