A string walks into a bar and hops on a bar stool.

He calls to the
bartender to order a beer.

The bartender looks at him and asks him, "Hey,
are you a string?"

The string nodded and the bartender commenced to kick
him out of the bar as they don't serve strings.

Out on the street, the string thought and thought until an idea hit him.

He
tied himself up in a knot and went back inside.

He hopped onto a bar stool
and motioned to the bartender.

"Are you the string that I just tossed out of here?" fumed the bartender.

"No," said the string, "I'm A-FRAYED knot."
