Overcharge

〔英語笑話〕——  Dentist：I'm sorry, madam, but I'll have to

                charge you 2 dollars pulling your son's tooth .

                Mother：Twenty-five dollars! But you said you

                only charged five dollars for an extraction .

                Dentist：I usually do. Be your son yelled so loud,

                he scared four other patients out of the office .


                                   

四倍收費

〔意譯成詩〕——  收費因何四倍增？牙醫道來有原因。

                你兒拔牙大叫喊，當堂嚇走四病人。
