All your bitterness and lies Sting like tears in my eyes And a thousand love-sick tunes Won't wash away the wounds from my mind You've been seen around, you're a new sensation You got a better deal, and you took his invitation You've been sitting on his lap and taking his dictation Oh but mercy, we used to love all day and drive all night Oh mercy, jealousy used to whet your appetite Oh mercy, we were low as dogs and high as kites Why must I plead with you darling Why must I plead with you darling Why must I plead with you darling For what's already mine Well my friends are indiscreet And I sing myself to sleep I don't mind the red wine Or the pick-up line as long as it's cheap Oh I ask you what's what and you say I'm all yours I ask who your friend is and you say it's Santa Claus I ask you to come home, you say you're tired of being indoors Oh but mercy, you know you signed on that dotted line Oh mercy, you signed yours and I signed mine Oh mercy, you said forever till the end of time Oh why must I plead with you darling Why must I plead with you darling Oh why must I plead with you darling For what's already mine I said why must I plead with you darling For what's already mine
