I keep telling my kids that they should wrap me in linen and dump me into a silty lake so that I have the best chance to fossilize, but they go on and on about "respect for the dead" and "police" and whatnot so I'll probably just end up in a box.
I tell them that I want simple with my remains, don't go nuts. That way you can spend all that extra money on a 30 foot marble statue of a sword wielding archangel Michael that shoots fire and shouts my name occasionally.
