When my brother-in-law also worked at my office, we created an eviction notice and put it on our boss' office door. We meant for the boss to find it but one of our coworkers did and called our boss at 11pm at night (and the VP of the company). hehe Thankfully, the boss and VP had a sense of humor about the whole thing and we didn't get in trouble for it. Our coworker was a bit of a moron - the notice was on plain white paper (not letterhead from the landlord) AND it wasn't on the main office door but one specific office door within the office. Doof.

A few weeks later, I laid down on the floor in said boss' office and my brother-in-law taped around me (with masking tape) so it looked like a chalk outline of a body at a crime scene. That was hilarious.
