Better yet, ban all metals that are used to make guns, knives, etc
Great idea man, Obummer's gonna love it. He may award you an autographed 5x7 photo of himself grinning like a possum eatin briar berries. You'll probably want to frame it and put it on your desk where everybody can see it.
What do you say, let's get the ball rolling by melting down our own "weapons of war", OK? I'll melt down mine if you will and we can cast the metal into a statue of Obummer standing in the Rose Garden with one foot on the Constitution and his other foot kicking Wayne Lapierre's butt. We might even get a medal of some kind, I want mine engraved to say "He gave his all (all his guns that is) to save mankind".
