"After dinner, Marcel Duchamp would take the bus to play at a chess circle and return late with Lydie, his first wife lying awake waiting for him. Even so, he did not go up to bed immediately, but set up the chess pieces to study the position of a game he had been playing. First thing in the morning when he arose, he went to the chessboard to make a move he had thought during the night. But the piece could not be moved. During the night Lydie has arisen and glued down all the pieces. A few days later, Duchamp and Lydie divorced, and he returned to the states."
