Lots of good trivia about Chuck Norris like: "Chuck Norris is the only man to ever defeat a brick wall in a game of tennis" and "Chuck Norris does not hunt because the word hunting implies the probability of failure. Chuck Norris goes killing."

2020 Update: The original site died, but the concept was way too popular so a copycat one appeared.
Spam subject lines recycled onto t-shirts for ironic effect.
2020 Update: the shop is closed, but the website lives on with photos of old content.
United States Central Command (USCENTCOM) galleries of images and propaganda leaflets, primarily of second Iraq war.

2020 Update: the gallery of propaganda leaflets seems to be no more. They still have a collection of photos but that's not as interesting to me.
In 1972 in Oklo, Gabon, while mining for uranium a very strange thing was discovered: the fossilized remains of a naturally occuring nuclear reactor. Later several other similar reactors were discovered, each dating back about two billion years. This is one of the few sites I've been able to find with explanations of the phenomenon and photographs of the site.

2020 Update: That site is dead, but there are lots of sites about the Oklo Natural Fission Reactors now. And there's a start-up company named Oklo trying to make small fission reactors.
