        String text = "Why shouldn't I work for the NSA? That's a tough one. But I'll take a\nshot. Say I'm working at the NSA, and somebody puts a code on my desk,\nsomethin' no one else can break. Maybe I take a shot at it and maybe I\nbreak it. And I'm real happy with myself, cus' I did my job well. But\nmaybe that code was the location of some rebel army in North Africa or\nthe Middle East and once they have that location, they bomb the\nvillage where the rebels are hiding... Fifteen hundred people that I\nnever met, never had no problem with get killed. Now the politicians\nare sayin', \"Oh, Send in the marines to secure the area\" cus' they\ndon't give a shit. It won't be their kid over there, gettin'\nshot. Just like it wasn't them when their number got called, cus' they\nwere pullin' a tour in the National Guard. It'll be some kid from\nSouthie over there takin' shrapnel in the ass. He comes back to find\nthat the plant he used to work at got exported to the country he just\ngot back from. And the guy who put the shrapnel in his ass got his old\njob, cus' he'll work for fifteen cents a day and no bathroom\nbreaks. Meanwhile he realizes the only reason he was over there in the\nfirst place was so that we could install a government that would sell\nus oil at a good price. And of course the oil companies used the\nlittle skirmish over there to scare up domestic oil prices. A cute\nlittle ancillary benefit for them but it ain't helping my buddy at\ntwo-fifty a gallon. They're takin' their sweet time bringin' the oil\nback, of course, maybe even took the liberty of hiring an alcoholic\nskipper who likes to drink martinis and fuckin' play slalom with the\nicebergs, it ain't too long 'til he hits one, spills the oil and kills\nall the sea life in the North Atlantic. So now my buddy's out of\nwork. He can't afford to drive, so he's walking to the fuckin' job\ninterviews, which sucks because the shrapnel in his ass is givin' him\nchronic hemorrhoids. And meanwhile he's starvin' cus' every time he\ntries to get a bite to eat the only blue plate special they're servin'\nis North Atlantic scrod with Quaker State. So what did I think? I'm\nholdin' out for somethin' better. I figure fuck it, while I'm at it\nwhy not just shoot my buddy, take his job, give it to his sworn enemy,\nhike up gas prices, bomb a village, club a baby seal, hit the hash\npipe and join the National Guard? I could be elected President.";
