I have a friend that, while he does not dress for Halloween, he makes sure that all the kids in his neighborhood (both big and small) are taken care of. He lives in a nice residential area, with lots of kids and parents who Trick or Treat.
Alongside candy for the little ones, he has a supply of airplane bottle-sized liquor. As parents send their kids up to his door for candy, he coaxes the adults up and surprises them with a bottle or two. Well, "surprise" is probably not an accurate term now as he's been doing this for years, and hands out hundreds of bottles each year.
