Example: There were these two dudes at an old job at a newspaper who fucking HATED each other. One was sports and the other obits. One day they got into it about how to cover a story about a local half-time show that involved some little dog that could do flips or whatever. The obit dude actually filed a formal complaint on the sports dude to the editor (not cool, really, because it wasn't any of his business). Well, we had a couple board games in the lounge area and later that night, when it was just me and the sports dude, I saw him grab all the fake money from the Monopoly game and then casually walk it in over and stuff it in the obit guy's desk. I asked him what he was doing and he said "I'm going to report him anonymously to HR for stealing from the company." And to top it off, he put the little dog monopoly piece in the obit guy's mailbox.

Total power move. Very weird. Pretty hilarious.
