I need some soap *SPOILERS*

First off, I love this book. I couldn't put it down that first day we got it assigned, so I finished it in one night. I think that it's a lot better than The Plauge. Fight Club speaks to me a bit more. The whole death and rock bottom thing, and giving up for a full release of mental stress, the total freedom to enjoy life by having nothing. It's all very interesting, and I like that message better than Camus' be aware of every moment by anxiety. Freedom > Anxiety. Plus the book has given me some interesting ideas of what to do with the giant bags of fat I have sitting in my freezer. I could use some soap. Plus the freon lock break, the CRT bomb (which is luckily becoming mostly unfeasible), the water pressure thing, etc. that stuff is very interesting. Not that I'll ever try civil terrorism. I felt that reading the book after the movie was really beneficial, I may have missed out on the wonderful narrative twist at the end but it was still nice knowing it cause it made a lot of stuff about the rest of the book make sense.
The one thing that has never made much sense to me was how Tyler knew as much as he did about soap, explosives, and terrorism. Was he running around experimenting and researching during the insomnia at the beginning of the book? How did he learn all that? Cause he had to teach it to the narrator. Although Chuck Palahniuk seems a little suicidal. His whole obsession with release from all the worries and problems of life via death is a little creepy.
