This Bush quote is reportedly from the Feb 25, 1990 Dallas Morning News:
I was not prepared to shoot my eardrum out with a shotgun in order to get a deferment. Nor was I willing to go to Canada. So I chose to better myself by learning how to fly airplanes. -- George W. Bush
I can't find a longer excerpt from the article on Google;
this site says it may be apocryphal.
Is anyone with Lexus Nexus or access to old copies of the Dallas Morning News able to confirm this, or even better, provide a longer citation? If this quote is on the level, it should be trotted out every time the Swift Boat people go on the air.
