Jeff, those are pretty harsh, but I like it.
I once worked in a store with about 12 people. The break room had a kitchen sink with a hand sprayer. One day I tied a rubber band around it, and when you turn on the water, BAM, you get blasted in the stomach. It went on for about a week with everyone "getting" everyone, including me and the owner. (It's very easy to forget to check for the rubber band). After that, the owner disconnected it and threw it away.
