A 40s swing party.
I would want to throw a Halloween party where everyone must come in costume.
It would be a movie marathon.
It would be like a baptism party where you dip demons under the water and raised out of the water re-born humanitarians. it would be a party to get rid of the democratic and republican party and replaced them with the re-born humanitarians that only have everyone's best interest at heart oppose to their own legacy and self interest....
