If for some reason you're feeling malicious and want the people in GS to fail the headless horseman event, but your "fail" button broke, have no fear.
First, you get on the roof of the inn. Choose your favorite method.
In case you're lame and don't know ANY methods of getting on top of the inn, first you
then you jump up and
then jump up again. Tada! you're on the roof.
Now, all you have to do is wait around until the headless horseman comes. When he sets the buildings on fire, simply stand near one of the patches of fire. You'll absorb all the buckets people throw at you.
enjoy!
