What are some of the most far-out and far-off predictions for the future? Maybe Al Gore's assertion that Manhattan will be under water by 2057?!

Help us create a collection of bad predictions by sending in ones you've heard that you think will look ridiculous 100 years from now. Dennis will select the worst predictions, and the final list will be placed into a safe and buried for 100 years so future generations can realize how ridiculous they are!
