I want to be buried (not embalmed) under a tree. (there are places you can do this)  Simon would either like the same or to be cremated.  He'd also like a memorial at his childhood church.

I want something to vaguely suggest that I'm evil.

Now the reason why is because I want people to think my grave is haunted.  If I die with lots of money I want a tomb complete with sound effects and I will expect and want my descendents to spread stories about me and my grave which they will then hotly deny.

Muwhahaha!
