Loose string

One day, a loose string went into a bar and asked for a drink. The bartender said:, "We don't serve loose strings in here. Get the hell out right now." So, then the string went into the men's room and proceeded to tie himself into a knot. Then he messed up his hair really good and went back into the bar. He bellied up to the bar and asked the bartender for a drink. The the bartender says:, Hey, aren't you the same loose string I just threw out of here? And the string replied: No, I'm a frayed knot.
