The ghosts in my office building keep ejecting the doorknob on the backdoor of the building. It's happened once every year since I started working there 4 years ago: we arrive at work one morning and the handle to the door is completely disassembled and lying on the ground.
It's an old house.
My boss says ghosts don't like doors and one time when she lived in a haunted house, a door that never wanted to stay closed unless it was locked just fell off its hinges. Those ghosts were sick of all that locking monkey business.
I can't say I blame them. If I were a ghost, I'd get tired of hanging out at my office, too.
