A string walks into the bar and asks for a beer. The bar-tender looks at it and says,"Sorry, we don't serve strings here." The string goes outside and finds a wino sitting by a dumpster and says" Hey....Do me favor? Tie me in a knot." The wino ties the string into a bow-line and string says," now frey both my ends for me." and the wino rolls the ends of the string on the pavement to frey each end. The string walks back into the bar and shouts at the bar-tender,"Hey...gimme a beer." The bar-tender looks around and asks,"Say...aren't you that string that was just in here?" "I'm a freyed knot." the string replied.
