From "Who Framed Roger Rabbit"

Toons:    'Smile Darn ya smile,
           You know this old world
           Is a great world after all.
           Smile Darn ya smile
           And right away
           Watch Lady Luck
           Pay you a call
           Things are never black
           As they are painted
           Time for you and joy
           To get aquainted
           Make life worthwhile
           So, Smile, Darn you smile!
