Author's Note: It's a pretty old joke:
A piece of rope walks into a bar and orders a drink.
The bartender tells him they don't serve drinks to ropes, and kicks him out.
Incensed, the rope ties himself in a knot and unravels both of his ends.
He then goes back in the bar and orders again.
"Hey", the bartender asks, "aren't you the same rope I just tossed out?"
"No", he replies...
