This one is not my style, but I have friends who appreciate it.  I looked for a page on how to actually dispose of a body, but they all kind of creeped me out.  There are some messed up people out there.  Instead I found this article on the Top 10 Weird Ways to Dispose of a Body http://www.livescience.com/history/top10-after-death-1.html .  Personally I hope to end up a brain in a jar attached to a computer (all part of my Master Plan for World Domination) but if I were to die I would hope it would be from spontaneous human combustion, if only to screw with all my friends who tell me it isn't possible, spare my family the hassle of arranging a funeral, and completely prevent any chance of coming back as a zombie.  Here is an article on spontaneous human combustion (SHC) http://www.castleofspirits.com/shc.html
