No 6. Pay toilets

Pay-toilets were abolished in America in the mid 1970s, but surprisingly New York had its first pay-toilet in 2008. It granted you 15 minutes of privacy for 25 cents; that’s 24 dollars a day. The best thing with this New York toilet was that after the 15 minutes were over, its door would automatically open, exposing the guests inside.

No 5. Leaded gasoline

Although, leaded gasoline was phased out in 1968, but for nearly 60 years the dangers of the element lead were ignored by the oil companies. Starting in 1920s, petrol, as we know it, contained the substance tetraethyl lead which boosted octane ratings and produced better engine performances than unleaded gasoline. Eventually, EPA, after its 25-year struggle phased out leaded gasoline in 1968.

No 4. Japan Smile Checks

In 2009, the Japanese Keihin Electric Express Railway started morning smile checks. Their employees were subjected to a software which would rate their smile on a scale of 0 to 100. The employees also had to carry an image of their ideal smile to help them get on track in face of any depressing situation. Truly mind-bending.

No 3. Microsoft Bob

This really is a great contender for the worst program ever created. In 1995, Microsoft released “Bob”; a big smiley face wearing glasses intended to replace Windows 3.1 and Windows 95’s desktop with a more user-friendly interface. It turned out to be a huge failure. Reasons can range from its huge price tag ($100) and high system requirement (a 486 with 8MB of RAM, in 1995!) to its overly cute presentation. Watch the video below for more on this cutesy assistant.
