Well, the whole thing started at the dawn of man   He was sittin' on a rock with a club in his hand   The very first time he laid eyes on her   She was dressed to kill in a saber-tooth fur      They hadn't invented any words to say   But he asked her in a primitive way   Do you wanna go back to the cave?      Back to the cave, make a little fire   A man and a woman and a primal desire   That's the way it is, that's the way it was   'Fore he made the wheel, man was makin' love      A million years later in a Texas bar   A cowboy's listenin' to a steel guitar   When she says, "Hi, my name's Irene"   She's wearin' bright red ropers and tight blue jeans      His eyes light up and his brain goes dim   He tries to be cool but she hears him   Say, you wanna go back to the cave      Back to the cave, make a little fire   A man and a woman and a primal desire   That's the way it is, that's the way it was   'Fore he made the wheel, man was makin' love      So you be Wilma and I'll be Fred   We'll throw the cat out the window   Put the kids to bed   Take a little trip through history      Do what's always come naturally   In the time machine at the end of the hall   We can be a couple of Neanderthals   Do you wanna go back to the cave?      Back to the cave, make a little fire   A man and a woman and a primal desire   That's the way it is, that's the way it was   'Fore he made the wheel, man was makin' love      Don't blame us for the way we behave   The only way we know, goes back to the cave   It's been done instinctively through pre-history   The road to the future, leads back to the cave   Back to the cave, back to the cave   Back to the cave
