    really? i use marbles made out of cast gunpowder. probably shouldn't fire those things at humans, but they make very good entertainment if you go onto the roof and shoot at the ground near people! scares the crap out of them!

    so? I already have most of the forces of the universe against me, why stop at only most? the worst that could happen is that i get spontaneously vaporized in the most painful way possible. what's to worry about?

    Please don't necro comments. It annoys everyone in the comment chain by sending email about something that they've left alone for a long time. There's also no reason to do so to say four words and a number.
