We don't have to do anything. You don't have to pay them money. They just give you free candy. As a child, I loved this, as you can imagine. Little Ronnie going to houses, "Trick or treat! Give me candy." So "trick or treat" -- "trick" means, like, a joke. And "treat" means like a snack or candy. A long, long, long, long time ago, this actually had a meaning, but we'll get to that later.
