Workin' Overtime

Boss man called me in again, he had some things to say:
Change your attitude or this is it.
I said 'Yeah boss, I been thinking you're absolutely right.
You ain't firing me, cos I just quit.'

I'm workin' overtime on a good time,
A man's gotta do what he's gotta do.
I might take all night long,
But I'll get the job done,
And I won't be satisfied 'til I get through.
I'm workin' overtime on a good time.

Now we've all got a talent, and I've discovered mine.
And I ain't gonna let it go to waste.
The smoke and lights don't bother me, the hours suit me fine,
It's a dirty job, but once I get the taste:

I'm workin' overtime on a good time,
A man's gotta do what he's gotta do.
I might take all night long,
But I'll get the job done,
And I won't be satisfied 'til I get through.
I'm workin' overtime on a good time.

Well now I've got good credentials, and a full case of ? ?,
With all of this experience, I'm overqualified but:

I'm workin' overtime on a good time,
A man's gotta do what he's gotta do.
It might take all night long,
But I'll get the job done,
And I won't be satisfied 'til I get through.
I'm workin' overtime, is it your shout or mine?
I'm workin' overtime on a good time.
