Chilean Miners -- Can Submariners Help?

NASA has been called in to help the team supporting the 33 Chilean miners trapped far underground, since it looks like they might be down there for up to four months. While there's no doubt that NASA would have some expertise in that area, I'm thinking that the U.S. Submarine Force might be even more helpful. After all, boomer patrols are about that long, in conditions about as cramped. While I don't suggest they have the miners run drills to help pass the time, I'm sure that Submariners can provide some good suggestions.

What were your favorite activities to help pass the time when you were on patrol?
