Applejack: I'm sorry, but I just couldn't let those spa ponies go another minute puttin' up with problems they didn't even know they had! Somehow they just got used to a huge bottleneck of ponies standin' around waitin'. An' I took one good look at that spa jam, and I knew I had to do somethin'! Sometimes the simplest things can just derail a whole operation. Whether it's a leaky pipe or doin' too much laundry. You can't just stick to the same old way of doin' things and expect them to get better. I mean, thinkin' you can is just plumb ridiculous. Right? It's funny when you realize the extra work they were doin' was actually makin' things worse!
