Your Passport(护照) Please!
   Mr. Hill arrives at London Airport at the end of a three-week holiday in France. Usually he wears a beard(留胡须). Since it has been hot there, he has taken it off(剃掉). But his passport photo shows him with his beard.
   An office looks at the photo for a moment and says: "Will you excuse me? Please sit down. I won’t keep you long." With this, he walks away, shows the photo to a second office and says: "I know that face." The second officer looks at the passport and asks where Mr. Hill has come from. When he hears that Mr. Hill has arrived back from Paris, the second officer smiled and says: "An Englishman with a beard stole a painting in Paris on Friday, and that man just looks the kind of man ..."
   Suddenly it comes to the first officer who Mr. Hill is. He returns to him and asks: "Did you teach at the No.2 . High School?" When Mr. Hill answers in surprise that he did, the first officer smiles and says: "I thought so. I'm Jack Smith. You taught me French. You haven't changed a bit."
