Here is a humorous story. Frank Smithson woke up and leaned over to turn off the alarm clock．“Oh，no!”he thought to himself．“Another day at that office；a boss who shouts at me all the time．”

As Frank went downstairs his eyes fell on a large brown envelope by the door．He was overjoyed when he opened it and read the letter inside. “Bigwoods Football Pools(足球赌博公司)would like to congratulate you．You have won half a million pounds．”

Frank suddenly came to life．The cigarette（香烟） fell from his lips as he let out a shout that could be heard halfway down the street．

At 11：30 Frank arrived at work．“Please explain why you're so late，”his boss said．“Go and jump in the lake,” replied Frank. “I've just come into a little money so this is goodbye．Find yourself someone else to shout at．”

That evening Frank was smoking a very expensive Havana cigar(雪茄)when a knock was heard on the door．He rushed to the door．Outside were two men，neatly dressed in grey suits．“Mr Smithson,” one of them said，“We're from Bigwoods Football Pools．I'm afraid there’s been a terrible mistake……”
