The use of the word "Dada" for the art movement, the meaning (if any) and intention of both the piece and the signature "R. Mutt", are difficult to pin down precisely. It is not clear whether Duchamp or Freytag-Lorinhoven had in mind the German "Armut" (meaning "poverty"), or possibly "Urmutter" (meaning “great mother”).[19] The name R. Mutt could also be a play on its commercial origins or on the famous comic strip of the time, Mutt and Jeff (making the urinal perhaps the first work of art based on a comic). In German, Armut means poverty, although Duchamp said the R stood for Richard, French slang for "moneybags", which makes Fountain a kind of scatological golden calf.[4]
