"So you think that you've got trouble
Well, trouble's a bubble,
so tell ol' Mr. Trouble to get lost.
Why not hold your head up high
and stop crying,
and don't forget to keep your fingers crossed.
When you find the joy of living
is loving and giving,
you'll be there when the winning dice are tossed.
A smile is just a frown that's turned upside down,
so smile and that frown will defrost.
And don't forget to keep your fingers crossed."
There are other lyrics available as well... just not sanctioned by any of the interested parties connected to 'The Dick Van Dyke Show'....
A word of caution - at the very end of the song, the lyrics suddenly become NS4W, so proceed at your own risk!
"Is it a naughty word, Daddy?"
"Well... yes, Rich. It is a naughty word."
