Fluttershy: "Um, Twilight? Do you have any better books on anatomy? I'm trying to study for my vet license renewal and...I found out Angel doesn't have anatomy. Or internal organs for that matter. Then I looked up this book and found out we don't have anatomy either! Or internal organs!" Twilight: "Uh, Fluttershy..." Fluttershy: "Have I been treating nonexistent tummyaches?!"
