[Verse 1]
The five o'clock whistle's on the blink
The whistle won't blow and what do you think?
My pop is still in the factory
'Cause he don't know what time it happens to be

[Verse 2]
The five o'clock whistle didn't blow
The whistle is broke and what do you know?
If somebody don't find out what's wrong
Oh, my pop'll be workin' all night long

[Bridge]
Oh, who's gonna fix the whistle?
Won't somebody fix the whistle?
Oh, who's gonna fix the whistle?
So my poor old pop will know it's time for him to stop

[Verse 3]
You ought to hear what my mommy said
When papa came home and sneaked into bed
And told her he worked 'til half past two
'Cause the five o'clock whistle never blew

[Trumpet Solo]
[Verse 2]
The whistle is broke and what do you know?
Oh, my pop'll be workin' all night long

[Bridge]
Oh, who's gonna fix the whistle?
Won't somebody fix the whistle?
Oh, who's gonna fix the whistle?
So my poor old pop will know it's time for him to stop

[Verse 3]
When papa came home and sneaked into bed
