A sea captain and his chief engineer were arguing over who was most important to the ship. To prove their point to each other, they decided to swap places. The chief engineer ascended to the bridge, and the captain went to the engine room. Several hours later, the captain suddenly appeared on deck covered with oil and dirt. "Chief!" he yelled, waving aloft a monkey wrench. "You have to get down there: I can't make her go!" "Of course you can't," replied the chief. "She's aground!" On a team we don't excel each other; we depend on each other.
