This site pretty much does what the name says & shows photos and occasional videos of awesome people hanging out together. (EDIT: I wanted to show you some actual pictures of Karl Lagerfeld & Kanye West, Shaquille O'Neal & Dr Ruth and Robert Redford & Dustin Hoffman, but BLOGGER SUCKS)
There are some hilarious photos, some incredible ones and some which show important/interesting things in history. For example, look for the photo of the physicists where there's about 30 of them and Marie Curie is the only woman. Or look for young Bill Clinton meeting JFK. I also like that it gives you a sense of the timeline of people more, by relating them to other famous people. It's really interesting to see Mick Jagger progress through from being a young dork with Peter Tosh, a hip young guy with James Brown to an elder statesmen with Madonna. It's also interesting just to see who has hung out with who throughout the past century. This sort of thing might make fame actually worth it!
