In case you missed it (I know I did), today was World Jump Day. 

An organization of people with nothing better to do decided to get everybody in the western hemisphere to jump at the same time, in an effort to see if the simultaneous impact of 600 million pairs of feet would shift the planet’s orbit. (For obvious reasons, this wouldn’t work if the entire planet’s population jumped at the same time, since the impact of mass jumping in the Eastern hemisphere would offset that of the Western hemisphere, and Earth’s orbit would remain constant — this is high science, don’t you know.)

The jump was scheduled for July 20, 2006 (today) at 11:39.13 UTC (Greenwich Mean Time), which translates to 7:39.13 a.m. Eastern Standard Time.

I’m no astronomer, but looking out the window, it doesn’t look like the Earth’s orbit has gone askew.

And it’s YOUR fault, because YOU didn’t participate.
