Rig up the coffin so if my obnoxiously excessive fundamentalist extended family ignores my wishes and decide to hold an obnoxiously excessive fundamentalist christian funeral one of my friends can push a button mid sermon and the coffin plays pop goes the weasel and out I go onto the floor. Jesus won't save you from cleaning up that mess, folks.
Jokes aside, chuck me in a hole, put a tree over the hole, buy some land around the hole and make a dog park. I love dogs. Dogs being around me forever would be a nice thing for me to look down on, assuming there's some kind of afterlife. Also, it'd make dogs happy! Happy dogs make everyone happy.
(except people who are scared of dogs, I guess.)
