A physicist, a chemist, and an economist are stranded on an island with nothing to eat. A can of soup washes ashore.
The physicist says, "Let's smash the can open with a rock."
The chemist says, "Let's build a fire and heat the can first."
The economist says, "Let's assume that we have a can opener."

(Paul Samuelson)
