We've all heard the scare stories about North Korea: the homemade nuclear arsenal built while their people starve and then aimed imprecisely at the rest of the world, a
|
||||
leader so deluded he makes L Ron Hubbard look like a man excessively overburdened with self-doubt and their deep-seated belief that foreign capitalists will invade at any
|
||||
moment and steal all their bauxite.
|
||||
The popular portrayal of this Marxist nation is something like one of the more harrowing episodes of M*A*S*H, only with the cast of wacky characters replaced by twitchy,
|
||||
heavily armed Stalinist meth addicts
|
||||
Cracked would like to take a moment to celebrate the good things about North Korea though, the things that the country's enemies prefer to suppress as part of their politically
|
||||
motivated jealousy. Like how no different to you and me, there's nothing every North Korean likes more after an 18 hour shift at the phosphorus plant than a nice beer to go with
|
||||
his dried fish ration. Ever attentive to its people's needs and in the twinkling of a decade, North Korea's leadership bought, disassembled, transported and rebuilt a British
|
||||
brewery in order to discover and reproduce the secrets of beer and then brew the sweet nectar for its hardworking people, up to 18 bottles at a time. And with minimal fatalities.
|
||||
When was the last time YOUR leader got a beer for YOU, American? (NB do not answer this question if you are Henry Louis Gates).
|
||||
Or how about the fried chicken restaurant that downtown Pyongyang boasts? Yes real chicken, fried and then delivered to your sleeping cube, with optional beer if you like! You
|
||||
don't even have to remove the feathers or pull out the gizzard yourself. Mostly. Americans must eat their fried chicken from a bucket, like swine, sold by a company so secretive
|
||||
that even the very blend of seasoning used is intentionally kept from them. And they call North Korea paranoid?
|
||||
And how many nations would entertain the syphilitic, bourgeois ramblings of Bill Clinton let alone permit him anywhere near their proud womenfolk? Only wise Kim Jong Il could see
|
||||
past Bill's many, many imperfections and treat him with the pity and kindness he deserves, accepting his feeble pleas to pardon the American spies rightly convicted of photographing
|
||||
the nation's sensitive beetroot fields.
