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 the cheerful chick-a-dee,
And whistle while you work

Come on get smart
Tune up and start
To whistle while you work

Yes, when there's too much to do,
Don't let it bother you,
Forget your troubles, try to be just like that cheerful chick-a-dee,
And whistle while you work

Come on get smart
Tune up and start
To whistle while you work
