      Three Frenchmen were sitting together to talk about their experience in England. The first said, "I once

heard someone shout, 'Look out.' I put my head out of a window and a bucketful of water fell on me. It

seems that 'Look out' may mean 'don't look out'."

      The second said, "I was once on a ship and heard the captain shout, 'All hands on deck (甲板).' I put

my hands on the deck and someone walked on them."

      Here's the third Frenchman's story. He once called early on an English friend and the maid (女仆) who

came to the door said, "He's not up yet. Come back in half an hour." When the third came back half an hour

later, the maid said, "He is not down yet." Then the third said, "If he's not up and he's not down, where is

he?" The maid said, "When I say 'He's not up' it means he has not yet got up, and when I say 'He is not

down yet' it means he has not yet come downstairs."
