In 1931, after the surrealist master Salvador Dali finished The Persistence of Memory, a painting in which a limp watch sags from a branch, Dali used to ask its viewers: "Three years from now, will you still remember this painting?"
一九三一年，超現實大師達利完成了畫作《持續的記憶》，畫面中一隻隻垂軟的掛錶，晾掛在枝椏上。他急急地問問人：「三年後，還會記得這幅畫嗎？」
