A rope walks into a bar, sits on the stool and asks for a beer. The bartender says "we don't serve ropes in here" and throws him out. The next day the scene is repeated and the bartender throws him out. The third day the bartender gets really upset and throws the rope out and tells him never to come back. The fourth day the rope stands outside the bar and tangles himself all up. Then he walks in, sits on the stool and asks for a beer. The bartender comes over, looks at him suspiciously and asks "Hey, aren't you that rope thats been coming in a bothering me"
The rope says "No, I'm a frayed knot"
