Wizard: As for you, my galvanized friend — you want a heart! You don’t know how lucky you are not to have one. Hearts will never be practical until they can be made unbreakable.

Tin Man: But I — I still want one.

Wizard: Back where I come from there are men who do nothing all day but good deeds. They are called phil . . . er . . . phil . . . er . . . er . . . good-deed-doers. And their hearts are no bigger than yours. But they have one thing you haven't got! A testimonial! Therefore, in consideration of your kindness, I take pleasure at this time in presenting you with a small token of our esteem and affection. And remember, my sentimental friend, that a heart is not judged by how much you love, but by how much you are loved by others.

Tin Man: Oh! Oh, it ticks! Listen! Look, it ticks!
