怎样才能保持婚姻长久？ (笑话)

/>
                                    WHAT MAKES A MARRIAGE LAST SO LONG ?
                                    A hu*****and asks his wife,
                                    You never argue when I get mad at you.
                                    How do you always control your anger?'
                                    'I clean the toilet,' she replies.
                                    'How does that help?' he asks.
                                    'I use your toothbrush.'

         老先生问他的太太，“这么多年来我发怒的时候你从来也不生气，你是怎么做到的哪？”
         妻子回答说，“我去刷厕所马桶。”
         “那管什么用？”老先生问。
         “我用你的牙刷刷呀。”
