If you died and could 'haunt' one object what would it be and why?

I've been watching Supernatural and Bobby died and his ghost is now attached to his old hip flask.
This got me thining (i know, dangerous thing to happen ;D), if you died and could be attached to one item what would it be and why?

And the changing room door in a la senza strore isn't a worthy answer.

I quite fancy being able to haunt our camper. Then at least i might get to go interesting places in it with its new owners.

 

I'd haunt the changing room door in a la senza strore NASA's Mars rover.... that'd be interesting to see what it sees

 

my x wife id make the BITCHS life a missery lol owen nw

 

One of those Mahoosive Ocean liners would be quite cool I reckon. get to travel the world see lots of sights, and they probably got a La Senza on board too,
