THE WORLDS FINEST GHOST

Not one to brag and certainly won't boast 
However I am the world's finest ghost 
I come out only when you are fast asleep
Casting an eye over the company you keep

Certainly won't scare you that is for sure 
As I come and go out of your front door 
Like other ghosts I will move things around 
Ever so quietly not making a sound 

What sets me apart from the others you say
I just don't let other ghosts get in the way 
For being top ghost comes at a price 
No one believes in me which ain't very nice
