'Two ropes walk into a saloon...they go up to the bar and ask the bartender for a couple of beers.
The bartender takes one look at them and says "You two get outta here! We don't serve ropes here!"

The ropes leave and go into the next saloon. They go up to the bar and order a couple of beers. The same thing happens. The bartender looks at them and says "We don't serve ropes here!! Git!"

Dejected, they leave. Then one rope had an idea! He said to his friend "Here, tangle me up and mess up the top of my head.."

Now, with confidence, the two ropes walk into a third saloon. They go up to the bar and say "Bartender! Two beers please!" The bartender eyes them carefully and says "Are you a rope?"

The rope replies "I'm a frayed knot!" '
