YMMV / Earth (The Book)

• Heartwarming Moments: The Afterword.
• Nightmare Fuel: In the science chapter, the Lithotome. Funny description/possible nightmare fuel in the note: ^note "An 18th-century tool doctors inserted through the urethra in order to relieve painful kidney stones. To put that in layman's terms, we used to shove pointy sticks in our dickholes on a rock-retrieval exploration dig."
• Unintentional Period Piece: As befits a book of its nature, many of the political and pop-culture references the book contains mark it as a product of the very early 2010s. The section on school, for example, contains a joke about iCarly, a show that would end in 2012.
