Three ropes walked into a bar, and one rope ordered a beer. The bartender responded by saying, “We don’t serve ropes in here!”
The second rope asked for a beer, and the bartender repeated, “Didn’t you hear me? We don’t serve ropes in here!”
The third rope disappeared for a moment, turned and twisted and tied himself, pulled out a few strings, fluffed them at the ends and returned to the bar in his disguise. The bartender said, “Hey, we don’t serve ropes in here, and aren’t you a rope?”
The rope replied, “No, I’m a frayed knot!” The bartender said, “Oh. That’s different. What will you have?”
