An early 1900s Death Valley town had 23 saloons (many basically tents). A visit to all, going 23 skidoo, meant having a very good time. Death Valley National Park interpreters have sometimes given as an explanation that the early 1900s mining town of Skidoo, California required that a water line be run from the source of water on Telescope Peak to the town – a distance of 23 miles. Most thought it would be easy, but the immensely hard rock along the course made it very difficult; it was eventually accomplished by a determined engineer. The term "23 Skidoo" was then used as a statement of irony, something like "duck soup": a reference to something apparently easy, but actually very difficult. Other interpreters simply say the 23 mile pipeline and the popular slang phrase is what gave the town its name. A jump rope rhyme that ended up "butterfly, butterfly, twenty three to do" dates to 1909 and may be the origin of this phrase. In The Literature of Slang (p. 38), W.J. Burke claims that the term "skidoo" was coined in 1906 by the musical comedy star Billy B. Van, citing an article in the Indianapolis Morning Star, March 31, 1906. In the book The Age of Uncertainty by John Kenneth Galbraith (Houghton Mifflin, 1977), Skidoo 23 refers to the abandonment of a town, Skidoo, in the Panamint Mountains of Death Valley National Park in California in the early 1900s. The number 23 apparently refers to the number of miles water had to be piped to the town and its sole reason for being; the mining of gold. After the mines were depleted, the town ceased to exist. In the book The Confessions of a Con Man as Told to Will Irwin by Will Irwin (B. W. Huebsch (New York) 1913), 23 relates to a rigged dice game called a cloth that travelled with small American circuses and carnivals in the latter part of the 19th century. It referred to a square marked 23 You Lose on the cloth which had 48 printed squares but only the one You Lose square. After making a big bet, the sucker was at some point persuaded that he had
