Firefly's first attempt at the "double inside-out loop" trick.
Firefly: I'm going for the double inside-out loop, Medley!
Medley: But its dangerous, Firefly!
Firefly: Danger is my life, Medley! (Firefly proceeds to perform the stunt and collides, head on, with Applejack and a basket she was gathering apples in, reducing said apples to sauce)
Applejack: (while lying in a pile with Firefly and the basket) Applesauce, anyone?
Firefly's attempts at convincing Megan to come with her to help the other ponies. While Megan's worries are voiced in a believable fashion, Firefly's assurances come off as rather lackluster and narmish.
The pilot's "Dancing On Air" plays during Firefly's first meeting with Megan. While Firefly's singing about how Megan had to be the one to save the ponies from Tirac, Megan's really not buying it, at least until the end of the song. Her gentle but slightly mocking snarks just make it.
Firefly: They'll be floating, lighter than a cloud... Megan: They'll be gloating, laughing right out loud... Firefly: The sight of you will send spirits flying... Megan: One or two may burst out crying...
Megan and Applejack exchanging confused looks during "Call Upon the Sea Ponies".
Escape from Catrina
Rep's initial method of getting the Rainbow of Light from Baby Moondancer involves shape-shifting into a nurse pony. It's hilariously unconvincing, especially with his unnatural pony coloration and stilted dialogue.
