So, legally, what can you do with a corpse?

In If I dug up a body, what would it look (and smell) like, Cecil mentions that by law a body does not have to be embalmed. Are there are other services a mortician performs that aren’t required? Do I even need a mortician? Could I hire a taxidermist to stuff Uncle Mort and stick him on the mantle?

I assume these would vary somewhat by state, so let’s run the gamut…

Yeah. Like if I gave permission in my will, would it be legal for my loved ones to throw a funeral celebration and cook/eat my body?
