With so many sightings of flies in urinals around the world, some readers have wondered about the urinal entrepreneurs enabling this choice architecture. Meet Doug Kempel, engineer and owner of Urinal Fly, aka. the “Fly Guy,” who sells flies, trees, and rifle-scoped targets for the benefit of men and janitors everywhere. (Price: Starting at 4 flies for $4.99 up to 100 for $59.99.)
Kempel also gives away a free four-pack of flies (like the one shown at the right) to anyone who asks, and advertises spillage reductions of up to 85 percent, slightly more than the results from the Amsterdam Airport experiment. Kempel, whose office is in Colorado, agreed to answer some questions about the flies, his elevator pitch, and where business is booming.
