- Preston B. Whitmore: For years, your granddad bent my ear with stories about that old book. I didn't buy it for a minute. So finally, I got fed up and I made a bet with the old coot. I said, "Thatch, if you ever actually find that so-called journal, not only will I finance the expedition, but I'll kiss you full on the mouth." Imagine my embarrassment when he found the darn thing.
- Preston B. Whitmore: Your grandad had a saying: "Our lives are remembered by the gifts we leave our children." This journal is his gift to you, Milo. Atlantis is waiting. What do you say?
- Preston B. Whitmore: Atlantis is waiting
