英語笑話:I can go home 我可以回家了

One day after school the teacher said to his students, "Tomorrow morning, if any one of you can answer my first question, I will permit him or her to go home
earlier."The next day, when the teacher came into the classroom, he found the blackboard daubed（塗抹） . He was very angry and asked, "Who did it? Please stand up!" "It's me," said Bob, "Now, I can go home. Good-bye, Sir."一天，放學以後，老師對他的學生們說：“明天上午，如果你們當中的任何一個同學能首先回答我的問題，我就准許他或她最先回家。”第二天，老師走進教室時發現黑板被塗得亂七八糟，他非常生氣的問：“誰塗的？請站起來！”鮑勃說：“先生，是我，現在我可以回家了，再見！”
