Krakow ... (inspired by a faceless FB friend)

+22

John Brown Krakow, the intellectual capital of Poland, where I had the privilege to serve as a USA dip 86-90. At that time, pollution was a real problem in Krakow (with the communist-built steel mill Nova Huta nearby). So the joke (humor being Poland's best defence, at least at that time) went: USA-USSR WWIII has exploded:

Two military officials in Krakow are struggling along with gears to spare them of radiation. They cross a devastated field, etc. By chance, they hit upon a hill, where three well-dressed gentlemen, sitting around an elegant table, are engaged in a game of bridge. The nervous radiation-protected military ask the gentlemen: "How come you're not spared of radiation?

Prompt, sans nervousness, answer: "We are from Krakow,  proshche pana."

Bad translation, 

"I beg you sir"... :)
