A pair of images showing a urinal with a fake fly etched into the porcelain is doing the rounds. (I'd guess it's been circulating for at least two years.) The images are accompanied by this caption:

In Amsterdam, the tile under Schiphol's urinals would pass inspection in an operating room. But nobody notices. What everybody does notice is that each urinal has a fly in it. Look harder, and the fly turns into the black outline of a fly, etched into the porcelain. It improves the aim. If a man sees a fly, he aims at it. Fly-in-urinal research found that etchings reduce spillage by 80%. It gives a guy something to think about. That's the perfect example of process control.

Apparently this is true. Schiphol Airport in Amsterdam does sport fly urinals. (Though I'd be interested in getting first-hand verification of this.) The Straight Dope reports that New York's Kennedy airport is considering using the same fake-fly technology.
