Sounds like a marching cadance (or running actually).
I've never heard those exactly words, but the one we usually do is very close, and those words could easily be adopted.
When I get to heaven
Saint Peter's gonna say
"How'd you earn your livin' boy?
How'd you earn your pay?"
I'll reply with a whole lot of anger,
"I made my living as an Airborne Ranger!
Blood, guts, sex and danger
That's the life of an Airborne Ranger!"
When I get to hell
Satan's gonna say
"How'd you earn your livin' boy?
How'd you earn your pay?"
I'll reply with a boot to his face
"I made my living sending souls to this place!"
edit: Forgot to say, this is for the US Army
