Couch

The couch at Andy Warhol's Factory was as famous in its own right as any of his Superstars. In Couch, visitors to the Factory were invited to "perform" on camera, seated on the old couch. Their many acts-both lascivious and mundane-are documented in a film that has come to be regarded as one of the most notorious of Warhol's early works. (imdb)
