Bottled Ghost

I bought a ghost.
It’s supposed to be a famous ghost.
But they say that about every ghost.
Who’s ghost is it?
Or, I suppose, was.
Who’s ghost was it?
No idea.
And it’s not like you can ask the ghost.
Open the bottle, and it escapes.
Ghosts don’t hang around.
Especially near the bottle that held them.
They get as far away from it as they can, as fast as possible.
So, there’s no telling who it was.
Or if there even is a ghost in the bottle.
I’ll just hold on to it.
And, some day, sell it.
