On the 15th of December, Occupy DC marched on a Christmas party for the GOP held by the notorious US Chamber of Commerce.
The plan was to "carol" the party with Occupy-themes Christmas Carols, but as lines of suit-and-tie GOP big shots passed between lines of protesters, booing and chants of "Shame" quickly took over.

The protest must have struck a nerve, because police ran their sirens at their most obnoxious setting all the way back to McPherson Square afterwards!
