Lyrics:

Smile
Show me where it hurts
'Cause you ain't got nothing to worry about
I said smile
No matter what you heard
There's a paler shade of grey my friend
So smile
Cause you ain't got nothing to worry about
Anything at all
You don't know anything at all

Smile
I said smile
Smile
I said smile
Smile

So smile
'Cause you ain't got nothing to worry about
Anything at all
You don't know anything at all
Smile
'Cause you ain't got nothing to worry about
Anything at all
You don't know anything at all

So smile
Smile
I said smile
Smile
I said smile
