After tonight's episode of The Colbert Report, Stephen Colbert will put his cast up for auction on eBay. Colbert broke his wrist in June while running around his set before the show began. The proceeds from the sale will go to the Yellow Ribbon Fund for injured military service members and their families as they recuperate at Walter Reed Army Medical Center and the National Naval Medical Center.

The Yellow Ribbon Fund is a favorite of Colbert's. He has already used his cast to raise money for the injured soldiers and their families by selling 'WristStrong' bracelets, a spoof of Lance Armstrong (and Nike's) LiveStrong yellow bracelets that raise money for cancer research. By the way, if you can't afford Stephen's cast, you can probably still afford one of his 'WristStrong' bracelets, which are for sale on his website.

Colbert's cast is signed by a wide variety of political and news figures: Nancy Pelosi, Tony Snow, Katie Couric, Brian Williams, Tim Russert, Bill O'Reilly, and Michael Bloomberg.
