"I can't say my past experiments with jet lag remedies have been very scientific. When I'm flying, I usually take an Ambien and listen to one of my own speeches on my iPod. I'm out in seconds.

But the video has been destroyed and I gave the beads back." - Senator John Kerry, chairman of the Senate Foreign Relations Committee
