You're sure of what your name is, you're sure of where you live
You know how much you make, ah, you know how much you give
You know where your house is, you know which road to take
Ah, but you're sure 'bout lots of things, look out, there's one mistake

There just ain't no doubt:
There's just one thing you're never too sure about

Never can be too sure about the girl
Oh, you can never be too sure about the girl
You leave her there, when you get back
She calls you Bill...when your name is Jack
Never can be too sure about the girl

You know about the truth, you can see it in her eyes
One thing you know about love--it'll cut you down to size
You hear what they tell you, do you do what you're told?
And if they say yes, does it mean it's really so?

There just ain't no doubt:
There's just one thing you're never too sure about

Never can be too sure about the girl
Oh, you can never be too sure about the girl
You leave her there, when you get back
She calls you Bill...when your name is Jack
Never can be too sure about the girl
You're ready for the thrill tonight
You think you'll take it slow
But she's forgotten more, boy, than you will ever know....

She calls you up in the middle of the night
She says she's lonesome, and alone
You're all revved up, finally some place to go
You knock on that door--nobody's home

Never can be too sure about the girl
Oh, you can never be too sure about the girl
You leave her there, when you get back
She calls you Bill...when your name is Jack
Never can be too sure about that girl

Oh, you can never be too sure about the girl
She'll drive you crazy boy, oh, no no
Never can be too sure about the girl
Never too sure
Never too sure
Never too sure
Never too sure
Never too sure about that girl
Ah, you can never be too sure about the girl
Ah, you can never be too sure about the girl....
