One day a string was walking down the street. He was really thirsty and decided to get a drink at a nearby bar. So he walks up to the bar tender and says, "I'd like a beer, please." The bartender looks at him like he's crazy and says, "I can't serve you, you're a string. Go on. Get out of here." So the string goes outside and thinks of a way to look more like a person. He knots himself toward the top and frays the string to look like a head with hair. He goes back inside and tries again. The bartender says suspiciously, "Hey, aren't you the string that was just in here a few minutes ago?" The string replies, "I'm afraid not!"
