Submarines - You Gotta Build 'Em - Section 10

Submarines, we gotta build ‘em. Pretty simple. We’ve never needed submarines built as much as we do right now. The important thing is they go down (this model currently doesn't go down). Section 10 wants us to make rines, we gotta make rines. Go Red Sox. Go submarines.
