A person comes out with a length of rope. He proceeds to give a knot demonstration some of which do not turn

the way he expects. He has creative and imaginative names for his knots such as the double hitch back loop tie,

clove hitch with a triple loop bight, etc. The last knot he ties is one that he says that a person can't loosen. The

more they try to loosen the knot the more it tightens. He demonstrates a temporary version of this around his neck.

He pulls on the knot when he is finishes and exclaims, "Oh no, I've tied the wrong knot, I've tied the permanent

version, and leaves the stage choking.
