Trephine
A trephine (/trᵻˈfaɪn/; from Greek trypanon, meaning an instrument for boring) is a surgical instrument with a cylindrical blade. It can be of one of several dimensions and designs depending on what it is going to be used for. They may be specially designed for obtaining a cylindrically shaped core of bone that can be used for tests and bone studies, cutting holes in bones (i.e., the skull) or for cutting out a round piece of the cornea for eye surgery.
A cylindrically shaped core of bone (or bone biopsy) obtained with a bone marrow trephine is usually examined in the histopathology department of a hospital under a microscope. It shows the pattern and cellularity of the bone marrow as it lay in the bone and is a useful diagnostic tool in certain circumstances such as bone marrow cancer and leukemia.

Drive On
by: Johnny CashI got a friend named Whiskey Sam
He was my boonierat buddy for a year in Nam
He said is my country just a little off track
Took 'em twenty-five years to welcome me back
But, it's better than not coming back at all
Many a good man I saw fall
And even now, every time I dream
I hear the men and the monkeys in the jungle scream
Drive on, it don't mean nothin'
My children love me , but they don't understand
And I got a woman who knows her man
Drive on, don't mean nothin', drive on
I remember one night, Tex and me
Rappelled in on a hot L.Z
We had our 16's on rock and roll
But, with all that fire, I was scared and cold
We were crazy, we were wild
And I have seen the tiger smile
I spit in a bamboo viper's face
And I'd be dead , but by God's grace
Drive on, it don't mean nothin'
My children love me , but they don't understand
And I got a woman who knows her man
Drive on, don't mean nothin', drive on
It was a real slow walk in a real sad rain
And nobody tried to be John Wayne
I came home, but Tex did not
And I can't talk about the hit he got
I got a little limp now when I walk
Got a little tremolo when I talk
But my letter read from Whiskey Sam
You're a walkin' talkin' miracle from Vietnam
Drive on, it don't mean nothin'
My children love me , but they don't understand
And I got a woman who knows her man
