Heartache lyrics

I was born by fire in a cold dark cave
In the age of the dinosaur
When a cave man caught his cave woman lovin'
On the missing link livin' next door
There was cryin' and screamin' and war drums a beatin'
And a wave o' violence
None o' them folks survived but me
And I been hangin' 'round ever since

'Cause I'm a heartache never see me comin'
I'll always take you by surprise
I'm a heartache hungry and huntin'
Someone I can eat alive
By the time you know I'm on you
Buddy it's too late
I'm a heartache (heartache)
[ Lyrics from: http://www.lyricsmode.com/lyrics/j/jamey_johnson/heartache.html ]
I watched you takin' off tonight
And I knew where you were headed to
I saw that sweet young thing you met
At that dirty ol' motel room
'Ell I'm gnawin' on your pretty little wife
Waitin' up for you at home
You don't even know it but I'm just savin' you for later
When I can getcha all alone

Yeah, I'm a heartache never see me comin'
I'll always take you by surprise
I'm a heartache hungry and huntin'
Someone I can eat alive
By the time you know I'm on you
Buddy it's too late
I'm a heartache (heartache)

From Anthony and Cleopatra
Samson and Delilah
To Jackie and JFK
To Elvis and Priscilla
Charles and Diana
I'd say I've had some pretty good days
And you may not believe it
But you and me son
Are 'bout to have some real fun
'Cause I'm comin'... ah I'm comin'

I'm a heartache never see me comin'
I'll always take you by surprise
I'm a heartache hungry and huntin'
Someone I can eat alive
By the time you know I'm on you
Buddy it's too late
I'm a heartache (heartache)
I'm a heartache (heartache)
I'm a heartache (heartache)
