Pinkie Pie's last minute save of Applejack:
"Simple!" she said. "Right after you left, my tail started in on a-twitchin', which always means something is gonna fall out of the sky!... I put two and two and two together and realized that the thing that was going to be falling out of the sky was Applejack! So I real quick rigged my gyrocopter up with a comfy passenger seat and a skyhook and then I invented some nightvision goggles so I could see in the dark to fly after you, and, wow, it looks like I was just in time, too!"
