"In this now infamous tape, exemplary of his early transgressive performance style, Acconci sits and relates a masturbatory fantasy about a girl rubbing his legs under the table. Carrying on a rambling dialogue that shifts back and forth between the camera/spectator and himself, Acconci sexualizes the implicit contract between performer and viewer - the viewer serving as a voyeur who makes the performance possible by watching and completing the scene, believing the fantasy."
