Apparently July 20th is World Jump Day. Some nut thinks that we’ll knock the earth off it’s current orbit and into a more environmentally friendly one with a mere 600,000,000 people jumping in unison.

I’d like to inform this individual that my previous efforts to change Chicago’s climate went without effect. If you can’t get 3 million people to open the windows of their superheated homes in mid-winter and warm things up for a while, then this certainly doesn’t stand a chance.
