An old rope and a young rope went into a restaurant for a bite to eat. The waitress said, “Sorry, we don’t serve ropes.”
So the two ropes left. The old rope tied himself into a knot. Then he scraped himself up and down a rough pole and went back in the restaurant.
The waitress said, “Hey, aren’t you that rope that was in here a few minutes ago?”
The old rope answered, “Nope, I’m a frayed knot.”
