Turn That Frown Upside Down

So, this one I made up for my niece, Valerie, when she was very young....

Turn that frown
Upside down
And be happy
Be happy
 
Turn that frown
Upside down
And be happy
Be happy
 
Look at me
Smiling at you
If you won’t smile
I’ll have to tickle you
 
Turn that frown
Upside down
And be happy
Be happy
Be happy and smile please
