Okay decided to put this one here rather than the bad jokes thread
Three pieces of rope are walking down the street when they decide to stop off at a nearby pub.
Outside the pub there's a sign that says 'we dont serve rope here'
Regardless, the first piece of rope walks in, asks for a pint but gets told to leave.
So the second piece of rope goes in, but gets the same treatment
The third piece of rope twists himself up a little bit before going into the pub. He walks up to the bar and asks for a pint.
The barman says "Aren't you a piece of rope"
The rope replies "No, I'm a frayed knot"
