This string goes in to a bar, and the bartender says, "hey, string, we don't serve your kind in here, get out!", so the string leaves. Outside, the string sees another string heading into the bar. Offering a warning, the first string informs the second, "they don't serve strings in that bar, I just got kicked out. The second string starts beating himself against a wall, and ends up in a knot, then proceeds into the bar. The bartender yells from behind the bar, "HEY, ARE YOU A STRING? WE DON'T SERVE STRINGS HERE!" To which the string replies, "nope, a frayed knot"
