If You're Happy的歌詞如下：
If you're happy and you know it
Clap your hands
If you're happy and you know it
Stomp your feet
If you're happy and you know it in your heart
Then let us know it
Come on let us know it
Oh yeah
Come on and wave your banner
Oh yeah
If you're happy and you know it
Then your face will surely show it
Come on and let us know it
If you're happy and you know it
Oh yeah
當你感到開心時，拍拍手
當你感到開心時，跺跺腳
當你心中感到開心時，盡情展現
讓我們知道你的開心吧
讓我們知道你的開心吧
來吧，讓我們知道吧
喔耶
揮舞著你的旗幟吧
喔耶
當你感到開心時，你的臉上一定會露出笑容
讓我們知道你的開心吧
當你感到開心時，你一定會知道它
喔耶
