Did you also have to bring as much money as possible to put under your plate? We had the Polish 12 course meal at our house this year. Granted, this is only my second experience with Polish Christmas, but my wife makes everyone bring money to put under their plate.
You get to take the money back home with you after the dinner, but I was sure hoping that some people would drink a little too much, forget their money, and then I would get a Christmas present of my own! :-)
