Marcel Duchamp's "Fountain"

According to one version of the story, this piece of art was bought from the J. L. Mott Iron Works by Marcel Duchamp and was just oriented at a 90 degree position for display.  Another version has it that Duchamp did not create this piece and was submitting it for a friend.  Whether it is considered a piece of art or not, it has got people thinking when they see a urinal in this position, in front of what may have been a fabricated background.  Duchamp was trying to shift the focus of art from "physical craft to intellectual interpretation."  The fountain has been lost, and since then, there has been reproductions in 1950, 1953, 1963, and an eighth in 1964.

This is considered to be the most influential artwork of the 20th century and replicas can go for as much as 1.7 million.  It's toilet.  Really?!?!
