Five go on a horrible adventure

Thanks to Five Books for asking me to chooses some disgust-heavy science fiction for reading pleasure. I revisited all of my choices in a splurge of reading before the interview, and ended up feeling a bit odd at the end of it. Brilliant books, though. And I rediscovered a short story that had been lurking in my mind, upsetting me every now and again, since my early twenties.

All recommendations of your own SF classics that make your insides feel weird are very welcome! Although I might give it a while before I revisit the sub-genre.
