Also, don't make stupid bets. Really.
Oh, and Applejack is just as capable of being a drama queen as Rarity, and as prone to insane leaps of logic as Twilight. "We lose the cider business" -> "We don't make as much money as we're used to" -> "We won't have anything to tide us over during the winter" -> "We'll lose the farm" -> "We'd better go pack up our things right now and move to Manehattan" or where ever they were planning on going. Maybe Dodge Junction?
Also, sticks and leaves make bad cider.
I didn't really like the episode that much, I think because I really hated the Flim Flam brothers, and not in the good way that you should hate an antagonist. It was more meta-hate? Rainbow Dash was funny, though. And the last scene when the FFB were getting their entirely predictable comeuppance.
