Here's a link to the sitge for "World Jump Day" -- an effort to have everyone in the world (or at least a few hundred million people) jump up at the same time to knock the Earth into a wider orbit, thereby lengthening daylight hours and reducing global warming.
Some people have way too much time on their hands. By the way, if you live in the Central Time Zone, we jump at 5:39:13 PM on July 20th.
