A piece of string walks into a bar and orders a drink. The bartender looks at him and says, We don't serve string here. So the string goes outside, twists himself up a bit, kind of roughs up his ends and walks back into the bar and orders a drink. The bartender looks at him and says, Aren't you that little piece of string that was in here a few minutes ago? The string says, No sir, I'm a frayed knot.
