We played a game where everyone brought in a wrapped white elephant and put it under the tree. The hostess typed up words from "The Night Before Christmas" and gave everyone a piece of paper with the word from the story on it. As she read the story, when your word came up you went up to the tree and got any present, or you could take a present (still wrapped) that someone else took. When the story was over, everyone unwrapped their present in turn. Then you could offer to trade with anyone else.
