How do I know when my ears are happy?
Cause I hear my favorite song
My feet start tapping and I start clapping
And I want to sing along
Let's clap if you're happy
Let's clap if you're happy
Let's clap if you're happy
Let's clap if you're happy
How do I know when my fingers are happy?
Cause they wiggle up in the air
They wiggle to the sky, they wiggle to the ground
They wiggle just anywhere!
Let's wiggle, if you're happy
Let's wiggle, if you're happy
Let's wiggle, if you're happy
Let's wiggle, if you're happy
How do I know when my teeth are happy?
Cause I smile bright and wide
You can see me giggle, you can see me laugh
My teeth don't wanna hide!
Let's laugh, if you're happy
Let's laugh if you're happy
Let's laugh, if you're happy
Let's laugh if you're happy
How do I know when my heart is happy?
Cause it beats like a little drum
It makes me dance; it makes me jump
I'm having so much fun!
Let's dance if you're happy
Let's dance if you're happy
Let's dance if you're happy
Let's dance if you're happy
How do I know if my hips are happy?
Cause they want to do the twist
They twist to the left. They twist to the right
Yes. You can twist like this!
Let's twist if you're happy
Let's twist if you're happy
Let's twist if you're happy
Let's twist if you're happy
You are happy happy happy
You are happy happy happy
You are happy! You're happy!
You are happy happy happy
You are happy happy happy
You are happy happy happy
You're happy!
