In the interests of science, I pressed on, finishing off the last bag. I experienced a bit more root beer butt; otherwise everything ended smoothly (no pun intended).

I took a final picture of my underwear. As you can see, there was a modicum of staining, but that was just from inadequate wiping. Rest assured, no anal oil was passed accidentally.

In conclusion, if you eat a fat that cannot be digested, it has to go somewhere, doesn't it? If you don't mind the occasional runny fart, the pools of melted butter on your toilet water, and the 1-in-50 chance of side effects such as severe abdominal cramping, then artificially-synthesized snacking pleasure can be yours.
