This Day in Failure: August 25

2017: U.S. president Donald Trump pardons Joe Arpaio, 85, who had been convicted of criminal contempt for disregarding a court order in a racial-profiling case. The move spares the former Arizona sheriff a jail sentence and sparks an outcry from civil rights groups.

2010: Professional golfer Jim Furyk oversleeps and misses his 7:30 tee time at The Barclays pro-am, resulting in disqualification from the tournament, held at Ridgewood Country Club in Paramus, New Jersey. More quirky golf failures.

1939: A little-noticed movie failure: After the Wizard gives the scarecrow a diploma at the end of The Wizard of Oz, the scarecrow recites the Pythagorean theorem: “The sum of the square roots of any two sides of an isosceles triangle is equal to the square of the remaining side.” But an isosceles triangle has two equal sides, so the square roots of one of those equal sides plus the third side cannot equal the remaining one. If he, uh, only had a brain, the scarecrow would have said: “The square root of the longest side of a right triangle is equal to the sum of the squares of the other two sides.”

1927: The U.S. Navy training dirigible Los Angeles is moored at the mast at Lakehurst, New Jersey, when a strong breeze lifts its tail dramatically. The cooler air at the slightly higher altitude exacerbates the problem until the vessel is in a comical-looking near vertical position, standing straight up on its nose.
