LOL My wife has already contracted that for me. She likes the idea of a Family Heirloom having actually been family. Sort of like using your grandmother's skin as a quilt, but not as Buffalo Bill. I'm okay with it as long as she donates all my organs first and lets my family view the body first. We're not overly morbid, but we do like having a plan.
"You mean this used to be Grandpa's ring?"
"Not quite dear..."
As an aside, our Dungeon Master's Dungeon Master just died, and his wife and friends had his ashes pressurized into a d20, and it's basically the coolest fucking thing ever.
