My top five pirate jokes:
A: The Gateway ARRRrrrch
A: Because it was Arrrrr rated.
Q: Why did the pirate buy a couch for his ship?
A: So he could be at his leisAAARRRRR
Q: What is a pirate's favorite planet?
A man walks into a bar and orders a drink. While he is waiting for it he spots a pirate sitting in the corner of the bar. The pirate has two wooden arms and two wooden legs. Naturally curious, the man gets his drink, walks over to the pirate and asks, "Excuse me sir, I hope you don't mind but I couldn't help noticing that you have two wooden arms and two wooden legs. You must have been involved in some fierce sea battles?" The pirate looked up, paused and said, "Arrrr no... me father was a tree!"
One of my favorite twitter follows is Somali_Pirate, a good natured pirate with a sense of humor.
