Pirate joke for kids

A pirate was on his ship and his watchman comes to him and says, "1 enemy ship on the horizont."

The captain says, "Bring me my red shirt, no men get injured  or die."

So the watchman comes to him and asks, "Why did you want your red shirt?"

The captain says, "Because if i get injured they won't see and keep on fighting."

So the watchman comes to him again and says, "20 enemy ships on the horizont."

The captain says, "Bring me my brown pants."
