  First Frenchman: I once heard someone shout, "Look out," I put my head out of a window and a basin of water fell on me. It seems that "Look out" may mean "don‘t look out."

  Second Frenchman: Once I was on a ship and heard the captain shout, "All hands on deck," I put my hands on the deck and someone walked on them.

  Third Frenchman: I once visited an English friend early in the morning and the maid who came to the door and said, "He’s not up yet. Come back in half an hour," When I went again for him, she said, "He‘s not down yet."

  "If he’s not up and he’s not down, where is he?" I asked.

  She said, "He’s still in bed. When I say ‘He’s not up ’ I mean ‘he has not yet got up’. When I say ‘He’s not down ’ I mean ‘he has not yet come downstairs,’"
