Two ropes

Two ropes walk in to a bar, one rope calls the bartender and says "Barkeep, let me get a couple of beers." The bartender says "I'm sorry we dont serve ropes in here."

Frustrated the ropes walk out and, since this was the only bar in town, they thought about it a little while when finally one rope says "I've got an idea." So he gets him self into a bind and frizzles his ends and walks back into the bar and says "Barkeep, can I get a couple of beers."

The barkeep says "Sure, but aren't you those same two ropes that came in here earlier?" The rope answers "Nope, I'm a frayed knot."
