Author's Notes:

Letter 79: Here.

To my most faithful student, Twilight Sparkle,

Twilight, you do realize Anon is messing with you, don't you? Rest assured my student, there is no statistically significant correlation between coat (or mane) color and brain size. Similarly there is no statistically significant correlation between coat (or mane) color and observed intelligence.

Remember, my student: Ponies, like other beings, are dumb because they are dumb, not because of what they look like.

Your loving mentor,
Princess Celestia

PS. There is a statistical correlation between ponies who have a majority pink coloration and Nevermind.
