Two strings walked into a bar and jumped on the barstool. Bartender comes over and one string says, "We would like 2 beers." The bartender looks at the strings and tells them they dont serve strings. <P>The strings walk outside and one string frays himself and ties himself into a knot. He walks back into the bar and jumps on the barstool and orders a beer.<P>The bartender looks at him and says, "Hey, arent you a string?" The string looks at the bartender and says......Nope, afraid(frayed) not(knot)
