Brave captain
One fine day, brave Captain Smith and his crew of sailors were sailing the ocean blue.
Suddenly, on the horizon, there loomed a ship with a skull and crossbones raised on the mast.
The crew was frantic, seeking refuge and asking the captain what to do.
Brave Captain Smith looked at the approaching ship for a moment and said, "Bring me my red shirt."
The call was taken up at once by a cabin boy. As soon as Captain Smith had the shirt in his possession, he ordered the man at the wheel to head straight for the pirate ship.
In the ensuing fight, the pirate ship was all but destroyed.
The sailors were recounting their individual triumphs afterwards when someone asked Captain Smith why he had asked for his red shirt before the battle.
He responded: "If I was wounded, I did not want your confidence to wane. This way, you would keep fighting no matter what happened to me."
The crew had a new found admiration for its captain, and they talked all night about his bravery.
About a week later, there loomed on the horizon 10 pirate ships. Once again, the crew looked to its captain for leadership.
Calmly, Captain Smith said, "Boys, bring me my brown pants!"
