Blame it on the ghost

This is when there is a horrible piece of art or gross food on the table that needs to go away but there is not a polite way to remove it. So, you destroy it and then blame it on the ghost.

Person 1: What happened to that horrid, inspirational cat poster the boss put on the wall?

Person 2: I couldn’t stand it anymore and ripped it off the wall! What will I tell her?

Person 1: Blame it on the ghost! There is always some spooky shit going on around here.
