Marcel Duchamp, the father of the Dadaist movement had another definition of art when he said the "Art is sh*t"... I kinda understand that in that what is left (art) is very much excretment...
Which reminds me of back during my social worker days... I had a fresh-outta-the-state-mental-hospital client who I assited in getting into a rooming house... The following day I got a call from the guy who ran it the rooming house... He was hysterical... Seems that my client musta taken Duchamp's definition of art way too literial... Nevermind the rest of the details but I believe that during all my years I never had to use the term "scatilogical art" in a case file except that one time... Thankfully...
