A rope walks into a bar...
 

So a rope walks into a bar and asks for a scotch and water. The bartender says "Im sorry, but we dont serve ropes here"
Being the alcoholic he is, he runs outside and pulls at his hair frantically, and practically ties himself in knots. He then walks back into the bar and asks for the drink again.

"Im sorry sir, but we dont serve ropes here"

"Rope?!? Im a-frayed-knot!!!"
