I remember when the current doofus-in-charge was put in to the white house. The Onion ran a story saying Bush would all but ruin the United States. This was not a terribly remarkable feat of prognostication, but I find it notable in light of its perhaps less obvious yet equally predictive fake companions. And as I'm re-reading it I realize that the way they got the details right is kind of remarkable.
Later The Onion created a fake story about how the rest of U2 was embarassed by Bono. About six months later a real story came out about how U2 had almost broken up because of Bono's extra-curricular activities. You can look all that up yourself if you want or just believe me and read on.
They did it again recently and this time I'm here with both links.
