A little thing we all can do to stop global warming

You've heard of the old infantry advice that troops shouldn't march in step while crossing a bridge? Keeps the bridge from falling down.

Well, the same principle is being applied for World Jump Day, Thursday, July 20 at 11:39:13 Greenwich Mean Time, or 6:39:13 am, Central Daylight Time. And it's all for a terrific cause: to halt global warming.

Yes, friends, with a simple lusty jump together with all of your neighbors and your town and all the people around the world...together we can cause the earth's orbit to shift just a skosh further from the sun. Oh, it's too marvelous to contemplate!

All it will take is for 600 million of us to jump up and down at the same instant – and, I presume, all on the trailing side of the earth – to boost us out to where it's cooler.

Are you going to jump on World Jump Day? I signed up. Have you? I can feel the earth move already!
