I can see your frown is disappearing
That's how I know you're happy
Deep inside your heart a crowd is cheering
That's how I know you're happy.
In your voice I hear some gleeful giggling
That's how I know you're happy
Down inside your shoes your toes are wiggling
That's how I know you're happy
Breaking through the gloom is your funnier face
Your light-up, bright-up sunnier face
I can see your eyes begin to twinkle
That's how I know you're happy
I can see your forehead has no wrinkle
That's how I know you're happy
Do I hear some laughter starting to fizz?
Where's that little smile?
Oh, there it is!
That's how I know,
By the way you let it show
That's how I know you're happy
