A piece of string walks into a bar and asks the bartender for a beer. The bartender says, "hey buddy didn't you see the sign? We don't serve pieces of string in here, now beat it"
sad and dejected the string walks out into the street..... Then he gets an idea. He ducks into the first alley and proceeds to tie himself into a bow and frills out his ends. He struts back into the bar. Slaps the bar top and says, " hey bar keep, need a beer over here"
The bartender says, "aren't you that same piece of string I just threw out of here???
The piece of string replies, No I'm a frayed knot ! (afraid not)
