THOSE DAMN FROGS: The French are at it again. Some "respected left-wing think tank" is pushing the bizarre theory that the Sept. 11 attack on the Pentagon was a hoax:

Thierry Meyssan's book ''The Frightening Fraud'' has topped best-seller lists. Meyssan, president of Reseau Voltaire, a respected left-wing think tank, theorizes that American Airlines Flight 77, which crashed into the Pentagon on Sept. 11, killing 189, did not exist and that the crash was staged by the government. ''I believe the American government is lying... No plane crashed into the Pentagon,'' he told France 2 television. Meyssan did not provide an alternative theory for what may have damaged the Pentagon.

I guess the hundreds of people stuck on that freeway that runs beside the Pentagon hallucinated the whole thing.

To their credit, the mainstream French media is scoffing at this crap. But the fact that the books is flying off the shelves is a little disturbing.
