Celebrities are "Hotter Than They Should Be" - And You Can Be Too

In a world where snarky, ironic t-shirts have become trendy fashion choices, the WWF (that's the World Wide Fund for Nature, not the pro wrestling circuit) is using them to its advantage. To raise awareness of its campaign against global climate change, the WWF has released a line of "Hotter Than I Should Be" shirts, replacing the "o" in "hotter" with a picture of a globe. They're very clever.

Now they've gone to the next logical step - having celebrities sign the shirts, and auctioning them off on eBay through eBay Giving Works! All the proceeds will go to support the WWF's global conservation initiatives, including the battle against climate change. Bidding ends on the 13th, so if you want an autographed shirt from Scarlett Johansson, Harrison Ford, Orlando Bloom, Paul Newman, Gisele Bundchen, Cindy Crawford, Charlie Sheen, or a host of others, and want to support a good cause at the same time, check them out!
