What comes out is the corn shell, which looks like corn unless you poke at it.

I've heard this, but never experienced it myself. No corn shell in my stool. I've also heard people say hot sauce is just as hot coming out as going in. I've also never experienced that (whew!). I do struggle with my weight, so maybe that's why? My gut microbes are extracting every bit of all the food I eat?
Depends on how much you eat, leastwise based on my own experience.
There was a point in my distant youth where I thought it was amusing to put as much spicy stuff on a meal as I could manage. Red pepper flakes, cayenne powder, tabasco, etc. It absolutely did burn going out--but only for about 5 minutes. I apparently ate enough to--err--make things go numb.
It was a very weird sensation and something I never did again given how unpleasant the whole experience was.
I'd imagine the people who--for whatever insane reason--participate in ghost pepper challenges experience something very similar if they can keep them down long enough to partake of the journey to completion.
P.S. - In all seriousness maybe that's why I've been able to be a vegetarian for 30 years without suffering from the ill effects people typically suffer, such as excessive gas. Maybe I really do digest cellulose better than most.
