We had a piping superintendent that left his boots under his desk when he went home at night. Some of the night shift guys lined the boots with plastic wrap, filled them with water, and put them in a freezer. They were back under his desk the next morning.
To say he was pissed was an understatement.
We used to do the same thing with hats. ...In the military, you can't go outside without a hat on, so they had to wait until it thawed.
