Lyra Heartstrings is a glorious mathematician, so it is no surprise when she decides to celebrate Pi Day with a pie-eating contest. As a critic of fancy-shmancy mathematics, Applejack bets Lyra that she can win the contest. Coincidentally, the contest also takes place on a day that Ponyville is to be a recipient of Princess Celestia, and things go downhill from there.

Part of the second SALT contest.
