Sorry But We Ran Out of Room

Go to a cemetery and find the tombstone of an old man who died within the last year. Look up the address of the old man's closest relatives. Buy a bunch of medical anatomy bones. Then drop the skull and bones on the porch of the closest relative.

Write on a sticky note-

"Ran out of room at the cemetery- Didnt think Gramps would mind."

Stick the note to the door.

The anger and outrage of the family member who finds what they think is Gramps old bones will be hysterical.
