Bush's Signature

I just discovered George W. Bush's signature (on the left) in high resolution on Wikipedia. Not only that, but unless it's one of his famous Bushisms, the text below the image clearly states:

"I, the copyright holder of this work [which I presume must be Dubya himself], hereby release it into the public domain. This applies worldwide. In case this is not legally possible, I grant anyone the right to use this work for any purpose, without any conditions".

Think I'll issue myself a Green Card and pardon all the prisoners at Guantanamo Bay. Any other suggestions?
