You sure know what your name is, you sure of where ya live You know how much you make, ah, ya know how much you give You know where your house is, you know which road to take Ah, you're sure 'bout lots of things, look out there's one mistake Chorus: 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 never can be too sure about the girl You leave her there, when you get back She calls ya 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 ya 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? Chorus 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
