賣笑的地方

午時三刻，烈日當空                                   
                                                       
  監斬官下令：「斬！」                                 
                                                       
  突然死囚一陣哈哈大笑！                               
                                                       
  監斬官問到：「你因何發笑？」                         
                                                       
  死囚遲疑片刻道：「專家沒說錯，                       
  笑一笑可延長壽命5秒！」
