Applejack: Dashie, did you eat the cookies I made for Cloudy's birthday party?
Dash, clearly lying: No.
Applejack: You're ugly when you lie.

Applejack: Then why are you ugly?
Richard Horvitz, who is our Random Narrator for the evening (don't question it): From that day on, Rainbow Dash swore to never tell a lie again. For she was so traumatized by the thought of Applejack thinking she was ugly, it scared her for life.
Richard Horvitz: Of course, Applejack never actually thought Rainbow was ugly. It was all just a clever ruse to trick Rainbow into being more honest. And it worked!... For about a week. That's about how long it took for Rainbow to get so drunk that she just kind of forgot.
