Okay here's my pirate joke.
A ship is sailing the high seas when the crows nest guy calls down, "Pirate ship ahoy!" The captain tells the cabin boy, "Fetch my reddest jacket!" The boy brings the reddest jacket he can find and the captain puts it on. They engage in battle and sink the pirate ship. The boy asks, "Cap'n, why did you call for your red jacket?" The captain says, "So that if I should be wounded in battle the crew would not notice the blood and lose their fighting spirit."
Next day the crows nest calls down, "Twenty pirate ships ahoy!" The captain tells the cabin boy, "Fetch by brownest pants!"
