You sure of what your name is
You sure of where ya 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
