So, a long time ago, there were these two magic horses. Together, they controlled the cycle of day and night, ruling over the kingdom of Equestria.

The cliff scene:

Twilight: Are you sure? Applejack:[in a ridiculous French accent] Sure as this is an authentic Southern accent! Twilight: ...I'm doomed, aren't I? Applejack: Just drop!
"TWILIGHT! WHERE THE HELL ARE YOU?!"
"Hasbro's gonna make a FORTUNE selling these as accessories!"
