A piece of string walks into a bar and asks the bartender for a drink. The bartender looks at him and says "sorry, we don't serve pieces of string here"... So the string went away and then suddenly had an idea. It tied itself in a knot and teased it's ends to disguise itself and walked back over to the bar to ask for a drink. The bartender looks at him and says "aren't you the same piece of string that came here just before asking for a drink?" the string looked at the bartender and said "no?............... I'm a frayed knot" hahahahaahhahahahaha
