Red Shirt, Brown Pants

There was a pirate ship...

The man in the crow's nest looked through his scope and yelled down to the captain, "ONE ship on the horizon!" The captain then said, "Get me my red shirt, for if I am wounded in battle, my crew will not see me bleeding and they will fight on." The man in the crow's nest looked again and yelled down to the captain, "TEN ships on the horizon!!!" The captain then said, "Get me my brown pants."
