Here we go!
SPOILER POST!
Starts with Rainbow Dash trying to beat Pinkie Pie in line for Cider Season, but she fails due to Pinkie camping out. Not to mention Pinkie told a few dozen others of the idea.
Well, good luck getting some, RD!

Edits to come!
EDIT 1: They run out before RD can get any. Big squabble later, the FlimFlam Brothers show up with a machine that can make cider MUCH faster than the Apple Family can make it.
The FlimFlam Brothers sing one of the longest advertising songs ever.
From here, it's the Apple Family vs. the FlimFlam Brothers. With Sweet Apple Acres at stake.
EDIT 2: The Challenge, make the most cider in one hour. Winner gets the rights to making cider for Ponyville.
The FlimFlam Brothers' machine can make 6 barrels of cider in the same amount of time the Apple Family can make one. Things are not going well.
EDIT 3: BEST CONTEST EVER!
First, the FlimFlam Brothers are winning. Then the Apple Family calls in extra help and then they start catching up. Then, the FlimFlam Brothers remove quality control to catch up.
In the end, the FlimFlam Brothers win due to the amount they made, but no pony wants it because it's filled with crap. So, in the end, the Apple Family's quality controlled cider wins.
Oh, and keep an eye out near the end for Bonbon's voice.
On to the review!!
