歌曲 Welcome Chris--当幸福来敲门插曲，历经磨难，终见阳光 歌手 The Pursuit of Happyness

歌词：“They all looked “happy” “Why not me? ” 幸福的答案是什么呢？没有答案，托儿所门外墙上的“happyness”的错误拼写，克里斯总是不断地强调：It's an "I" in "happiness."There is no "y" in happiness.去掉引号，隐含着一句：It's an I in "happiness"　,there is no why in happiness.是呀，幸福没有为什么，只有“我”去追寻。
