The entire “Martian” piece is great, but the line “I came here in peace, seeking gold and slaves” is even better on its own. It has a perfect setup and punchline, which are exactly the same length, creating a pleasing symmetry: five syllables of set-up and five syllables of punchline. The line isn’t iambic pentameter, but the ten syllables give it that Shakespearian feel. The language is simple, and the contradiction is massive. I dare you to write such a short, plain, ridiculous line.
