There's an old saying that, if you like to eat sausage, never watch it being made, or you'll never be able eat it again. The gist is that it's a very messy process, might even turn your stomach, but the end result is yummy.
So, the intended allegory was that, while getting the job done may be messy, we can have faith in the result if we just have a strong stomach.
You dig, babe?
