Duchamp and his alter ego

"Why Not Sneeze Rose Sélavy? consists of a small bird cage, fitted inside with four wooden bars, containing a thermometer, a cuttlefish bone and one hundred and fifty two marble cubes cut to resemble sugar lumps. On the underside of the cage, in black paper-tape letters, the title and date of the work have been affixed, with each word placed on a separate line:

WHY
NOT
SNEEZE
ROSE
SELAVY? 1921" http://www.tate.org.uk/art/artworks/duchamp-why-not-sneeze-rose-selavy-t07508   

 "In the 1950s Duchamp created a series of four small-scale 'erotic objects': Not a Shoe (1950), Female Fig Leaf (1961), Dart Object (1962), and Wedge of Chastity (1963). Not a Shoe is thought to be an early version of the wedge section in Wedge of Chastity. After Duchamp's death, these pieces were found to be connected with Etant donnés, or Given, the piece on which Duchamp worked in secret between 1946 and 1966 and which is now installed at the Philadelphia Museum of Art. Etant donnés can be seen as a three-dimensional realisation of the action alluded to in The Bride Stripped Bare by her Bachelors, Even. Etant donnés consists of an elaborate erotic tableau of a female nude with legs spread, and is viewed through a peep-hole in a wooden door.
The French title, Objet-Dard, is a pun on 'objet d'art', or work of art. The word 'dard', or 'dart', suggests masculine aggression, but the limp phallic form could as easily refer to impotence as to sexual satisfaction. Dart Object was based on a part of the mould of Etant donnés that had been situated directly under the breast of the 'bride', holding the 'skin' in place. After he had finished with the mould, Duchamp broke it, and the shape of one of the broken pieces gave Duchamp the idea of using it as a work of art. Inverting the scriptural source in which Eve is created from Adam's rib, Duchamp creates an emphatically male symbol from a rib-like structure in a model of a female figure. The raised strip along the upper surface, painted silver, echoes the strip of lead inlaid in the original plaster." http://www.tate.org.uk/art/artworks/duchamp-dart-object-t07280/text-summary

Not really sure what to make of all this...I like the idea that Duchamp wanted to defy the rules of art and change it's meaning, and the fact that he created this alter ego is cool, but personally I don't really like these pieces of art, although I think the ideas behind them are great! I respect the point he's trying to make, but I wouldn't want these pieces in my house, put it that way!
