Yeah, that is a key... Having friends with an oz. of life left in them... My buddy Dan is 27, but still has the mentality of a 21 year old guy, so he's all about going to clubs/bars... At least a couple nights a week. He and his girlfriend both have their costumes for this weekend, and my other buddy Eric lives for Halloween.
He's in prosthetics as his profession, so he goes all out every year. Last year his costume was a Satan that had platform prosthetic legs, an unfolding set of wings on tracks/pullies that were hidden, goat-skin leggings/hoofs, a form-fitting prosthetic body-suit... All hand-made.
This year it's an elaborate Jack Sparrow and his girlfriend's going as that woman from the PotC movie.
Myself. A shark who'd had 1 too many...
