To have sex on every continent, hence to cir-cum-navigate.
Finally! My wife and I have always wanted to circumnavigate the Earth. We finally took this cruise to Antarctica, and when they finally let us off we did it! The best part is you can just finish anywhere and no one will notice because everything's all white.
