Thankfully the rest of the world assumed that the Irish were crazy, a theory that the Irish themselves did nothing to debunk. They had somehow got it into their heads that each fairy lugged around a pot of gold with him wherever he went. While it was true that LEP had a ransom fund, because of its officers' high-risk occupation, no human had ever taken a chunk of it yet. This didn't stop the Irish population in general from skulking around rainbows, hoping to win the supernatural lottery.
