Whistle while you work
Just whistle while you work
Put on that grin and start right in
To whistle loud and long
Just hum a merry tune
Just do your best then take a rest
And sing yourself a song
When there's too much to do
Don't let it bother you
Forget your troubles
try to be just like a cheerful chick-a-dee
And whistle while you work
Come on,get smart
Tune up and start
To whistle while you work
