the second rope tries a disguise, but the same thing happens... "Sorry, we don't serve your kind, please leave"...

Well, the third ropee was watching this and says "I'll get in, watch..." So hee goes around the corner, ties himself into a knot, and frays his ends a bit... He goes in, sits at the bar. bartender says "Hey, aren't you a rope?" he replies, "Nope... 'Fraid not." . . . The End.
