每当听到 莫文蔚的if，我便会想起求婚事务所-情书那个单元.述说了一对恋人相爱却像鱼与鸟一样，永远相隔．
小鸟(大S)和树(蓝正龙)有次吵架，小鸟离开了他与树家．来到她和树经常去的网吧．看见了树写给她的一封邮件．树说：我的青春小鸟，已经３天没有收到你的信了．你飞去哪了？今天无意尖又哼起面包合唱团的if，发现里面有一些歌词，正是此刻我心情的写照。
If a man could be two places at one time
I'd be with you
Tomorrow and today
Beside you all the day.....(是第９集中的原词）
小鸟回信说道：树，对不起。结婚是迷思，那只是个形式而已。我不该固执的为了一场虚无的婚礼，而忽略了两个人在一起的真意。不管未来我们是分离或相守，只要你一直把我放在心中，那就是最伟大的爱情。那会声国任何一场盛大浪漫的婚礼。
If the world should stop revolving
Spinning slowly down to die
I'd spend the end with you
And when the world was through .....（是第11集中的原词）可惜当树发现这封信时，小鸟已经．．．无法再回到他身边了．

原唱：bread 　歌名：if　(下载地址:http://fifa2006.wz66.com/uploadfiles/2007-5/521436865.mp3 )
If a picture paints a thousand words,
then why can't I paint you?
The words will never show the you I've come to know.
if a face could launch a thousand ships,
then where am I to go?
There's no one home but you, You're all that's left me to.
And when my love for life is running dry,
you come and pour yourself on me.
If a man could be two places at one time,
I'd be with you.
Tommorrow and today, beside you all the way.
If the world should stop revolving spinning slowly down to die,
I'd spend the end with you. And when the world was through,
Then one by one the stars would all go out,
then you and I would simply fly away
