In Santa Monica, All the people got Modern names like Jake or Mandy And modern bodies too In Santa Monica, on the boulevard, You'll have to dodge those in-line skaters Or they'll knock you down I never felt so lonely Never felt so out of place I never wanted something more than this But on the telephone line I am anyone, I am anything I want to be I could be a super model or Norman Mailer And you wouldn't know the difference On the telephone line I am any height, I am any age I want to be I could be a caped crusader, or space invader And you wouldn't know the difference Or would you?

在Santa Monica，在那林荫大道，你躲闪着身边的溜冰者，以免自己被撞翻在地。我从未感到如此的孤独，从未感到如此迷茫。我从未有过如此的感觉。然而在电话里我可以装扮成任何人，装扮任何我想装扮的人，我可以是一个超级名模，也可以是一个普通的诺曼第邮差，而你能察觉到其中的不同吗？在电话里我可以是任何身高，任何年纪，只要我想，我可以是一个身披斗篷的十字军战士，亦或是一个外太空的入侵者。
