After spending two weeks on a survival hike in the desert a man gets into town and the first place he goes is the local bar. Looking dirty and tattered he walks up to the bar and orders a beer. The bartender gives him the once over and says,"show me the money first." Explaining that his pickup man would not be there for an hour he asks if he could run a tab till then. The bartender looks at him again and replys,"no money no beer". Trying to be get his drink he asks,"can I win a beer on a bet? The bartender replys, "sure". Looking around the room he sees his chance and says,"if I drink 1/2 of that spitoon over there can I get my beer"? Bartender answers you drink 1/2 of that spitoon and you got two beers". Walking over he picks it up the spitoon and begins drinking. When he sets it down it is clear empty. In astonishment the bartender states,"I tought you were only going to drink 1/2". To which he answers," yeah but I hit a long string and I couldn't stop".
