Marriage is a two-headed transplant, Sometimes thats how it seems. When the sex wears off its all give and take, And its good-bye to all your dreams. One head wants to go to a movie While the other wants to stay at home, And just like a two-headed transplant You get the feeling that youre never alone. Mr. and mrs. horrible are an example of what I say. They used to be so in love, now they fight so much That theyve frightened all their friends away. They never get visits from neighbors, Theyve alienated everyone. And what started off as all cuddles and kisses Has finally become A labour of love, labour of love. The torment, the worry and woe, Loves full of fears, bruises and tears, Thats the way that a true love grows. Its a labour of love, labour of love. Its a struggle, without a doubt, But if they keep on trying, screaming and crying, Somehow theyre gonna work it all out. It turned into a two-headed transplant, But it started off with "here comes the bride." But cut off one of the heads and youll soon find out That the other just couldnt survive. Because they couldnt stand to be separated They still each others to have and hold. Anyone who thinks the transplant is easy Really ought to be told Its a labour of love, labour of love. The torments, the worries and whoas, The battles, the fights, the bruises and bites, Thats the way that a true love grows. They took the vows, for better or worse, And they had it blessed by heaven above, But what started so brightly as a tender romance Turned into a labour of love. Turned into a labour of love.
