HMS Surprise: PIRATES!
To anyone in the San Diego area, there is a ship called the HMS Surprise that was used to film "Master and Commander" (have to see the movie now!) and it has been converted into a pirate museum. And there are all kinds of things that tie into POTC.
Grog: any drink made with rum
Pieces of 8: Size of an American 50cent piece, sometimes square in shape rather than round. Proper name "eight reales" which were shipped back to Spain to fund their empire.
They even had people walking around in costume saying "ar." It's a lot of fun and I highly recommend it. You tour that, a Russian sub, and three other ships.
Oh, and this was disturbing. It said that male and female pirates both were often covered in tar before being publicly executed.
