A string walks into a bar, and says give me a shot and a beer, the bartender looks at him and says "you are a string, we don't serve strings in here." So the sting goes out to the street, and makes one end of himself all fuzzy, and then ties himself up. He goes back into the bar and asks the bartender for a shot and a beer, the bartender looks at him, and says "aren't you the string I just threw out of here?" The strings looks at the bartender and says "no I'm a frayed knot!"
