Is Mike Huckabee Serious?

Former Presidential candidate Mike Huckabee was speaking Friday to the NRA, when there was a loud bang. Instead of continuing his speech, he aimed an assassination joke at Barack Obama. *crickets*

Huckabee apologized for his "offhand remark," saying it was not "intended to offend or disparage Senator Obama." Obama, for his part, refused to comment. Because what's funnier than killing a U.S. Senator?! What poor taste.
