     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 ..."
