H.L. Mencken seemed to have a gift for cynicism — even the gold he touched turned to lead. In December 1917, as a joke, he composed a fictional history of the bathtub for the New York Evening Mail. The article, “A Neglected Anniversary,” was preposterous, saying that the bathtub had been introduced to England in 1828 and to the United States 14 years later, and that Millard Fillmore encouraged its acceptance by installing one in the White House in 1850.

To Mencken’s horror, the story was widely accepted as fact, and it’s still quoted today as an authoritative source. Mencken said:

“The success of this idle hoax, done in time of war, when more serious writing was impossible, vastly astonished me. It was taken gravely by a great many other newspapers, and presently made its way into medical literature and into standard reference books. It had, of course, no truth in it whatsoever, and I more than once confessed publicly that it was only a jocosity. … Scarcely a month goes by that I do not find the substance of it reprinted, not as foolishness but as fact, and not only in newspapers but in official documents and other works of the highest pretensions.”
