(Lyrics by Morey Amsterdam*)
So you think that you've got trouble?
Well, trouble's a bubble
So tell old Mr. Trouble to get lost!
Why not hold your head up high and
Stop cryin', start tryin'
And don't forget to keep your fingers crossed.
When you find the joy of livin'
Is lovin' and givin'
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
(* In a 2010 interview on National Public Radio, Van Dyke revealed that Morey Amsterdam wrote a set of lyrics for the show's theme song)
