Another reference that I haven't seen mentioned yet is when Alcatraz wakes up on the ground and says something about it not being his friend. This is a reference to the Hitchhiker's Guide to the Galaxy where the improbability drive turns a missile into a sperm whale, which then plummets to the planet. At the end, the whale thinks: "And wow! Hey! What’s this thing suddenly coming towards me very fast? Very very fast. So big and flat and round, it needs a big wide sounding name like … ow … ound … round … ground! That’s it! That’s a good name – ground! I wonder if it will be friends with me?" I'm rather surprised no one else has mentioned this, since the humor in Hitchhiker's Guide and Alcatraz are so similar, so they should attract similar readers...
