The first time you roll the odds are one in twelve. Second time the odds are one in eleven. Third time, one in ten, and so on. If you roll the dice twelve times without rolling a twelve, you will never, ever roll a twelve again. Ever. And that only means one thing. Those dice have been cursed. Once you have determined you own cursed dice you have three choices. 1...Carefully replace them in their original packaging and return them to the store for a full cash refund, take that cash to your nearest church and donate it all in their little donation box. That is the safest method and the one I endorse. 2...Wrap the dice in aluminum foil. A lot of foil, like two or three full rolls of foil, preferably along with some fist sized stones, for added weight. Take a cruise to another continent and drop the package into the middle of the ocean. Watch it sink. Pray as you do. This is effective but expensive. And lastly, number 3....if you are emotionally attached to these dice and would like to keep them, bring them to an exorcist. This may be highly effective but is also extremely dangerous. You would need an extremely competent exorcist to perform the correct ritual. I can't even go into all the ways this could go wrong. I advise against it. Good Luck !!!
