Flutterby™! : dying isn't easy, comedy is still hard

In light of the discussion about evidence-based medicine and a few other things that are going on in my life (Charlene's biological mom has had a close-call which, in a merciful world, would have taken her, and there's now a lot of "how do we arrange for ...?" questions raised), it seems a reasonable thing to make plans for my eventual demise. Not that I'm expecting it any time soon, but when it does I'd like to be remembered fondly.

So, I've often said that I'd like my body to be used by medical students for practical jokes, but where does one start to investigate ways to dispose of a body so that it'll be of most use to the world, and be least likely to allow the funeral industry to suck any other assets from causes that I might actually like my resources to support? And, short of tattooing "do not resuscitate" on my chest, what's a good resource for putting together a living will?
