Prefect

Sidorovich made an offer to a rookie stalker. "Listen, sonny, I was given a new suit from the Kiev Research Institute. They wanted me to test it. They claim that it protects fully from radiation, 100%. But I am an old man, sitting here all day. Why don't you take it, test it for several days, and then come back with your results. I can give you a discount on this one, let's say, half price." The rookie takes the suit and goes outside. Several days pass. One morning, the rookie enters Sidorovich's bunker, angry as an snork, throwing the suit on the table in front of the trader. Sidorovich looks at him with suprise. "So?! What is it now?" "I don't want this crap!" "But why? Does it protect?" "Yes, you bet it does." "Completely?! 100%" "Yes, 100%." "So what then?" "The whole Zone is fighting radiation disease vith vodka, but I'm the only poor fool staying sober for 4 days!"
