A Rope goes into a bar.
Bartender says: "Hey - we don't serve ROPES in here."
So the Rope walks outside, unties his top, pulls strands down like hair and walks back in thinking "He'll NEVER recognize me."

The Rope goes to the bar.
Bartender says, "Hey! Aren't you that Rope that was just in here?"

Rope replies solemnly, "Nope ~ 'frayed knot!"
