The bartender shouts at him, "get out, we don't serve string!"
So the length of string hangs out just outside. He asks a passerby, "could you please roughen up my edges?" The stranger obliges. He asks the next one, "could you please tie me up?"
Our friend walks back into the bar. The bartender bellows out, "hey, didn't I tell you we don't want any string in here?"
And the string says, "I'm a frayed knot."
