he's gonna do you in lyrics

I knew a man, his name was Lynn
He had a sweet voice, he drove a Rolls Royce
He wanted inside me, I said nolet's be friends
He waited for a while, he like the challenge
But when it was over, when he didn't win
He found a warm place inside of my friend
He found a warm place inside of my friend
He found a warm place inside of my friend

He's gonna do you in, child, he's gonna do you in
He's gonna do you in, child, he's gonna do you in
When the night is over, and the morning begins
He won't even know your name, girl

I knew a boy, his name was Troy
He was a young thing, acted so strangely
He wanted inside me, but I wouldn't give in
He tried to play it cool, thought I would give it up soon
But when it was over, when he didn't win
He found a warm place behind another man
He found a warm place behind another man
He found a warm place behind another man

I said you gotta be careful
You just don't know who's who anymore
Once you think you know someone, you find out he's somebody else
You gotta watch people nowadays
They say they'll be there for you 'til the end
But they really got plans to do you in
Yes, they do, they've got a motive
They're plotting on you, they're plotting on you
Yes, they do, take it from me, I know
