Drawn from a thread over at Balloon Juice, here are the finalists for the best headlines of 2007. (Yes, I know we have more than half a year left -- assuming the president doesn't unveil that Rapture Accomplished banner -- but these are going to be impossible to top.)
The first headline displays tongue-in-cheek humor. The second one, well, you don't want to put your tongue there.
Feel free to add your own suggestions in the comments below.
