Piece of string heads into a bar, jumps up on a stool and tries to order a drink. The bartender tell the piece of string the bar does not serve string and told the piece of string he had to leave. The piece of string heads out of the bar and goes down an empty alley. The piece of string pulls a few strands from either end and twists his body, then he heads back into the bar and jumps up on a stool. The bartenders takes one look at him and asks "aren't you the piece of string I just tossed out of here?" The piece of string looks at the bartender and says no, I'm a frayed knot
