A piece of rope walks into a bar and orders a drink. The bartender says "beat it! we don't serve drinks to the likes of you", so the rope leaves and ties himself in a figure 8 and unravels his end a little bit, then he goes back in and sits at the bar. The bartender looks up and says "Hey aren't you the piece of rope I just kicked out!" and the piece of rope says "frayed knot".
