When we were posted to Lima, Peru, we returned from home leave to find literally EVERYTHING in DH's office that wasn't bolted to the floor stacked up on his desk - his chair, the floor fan, a small safe, a dozen telephone books, his visitor's chair...you name it, it was there! On the front of his desk was taped a sign that said "Things got a little piled up while you were away!"
He knew who was the perpetrator and got his own back when he put the perp's shoes in the freezer in the refrigerator in the boss's office. (Perp had a bad back and felt better whe he walked around the office in his sock feet.)
