Go as your favorite Founding Father :)
Or, if you're feeling particularly vexed, as one of the Sons of Liberty....
If ye love wealth better than liberty, the tranquillity of servitude than the animating contest of freedom, — go from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains sit lightly upon you, and may posterity forget that ye were our countrymen!
Samuel Adams
