I was walking through our apartment and stepped on a thumbtack. I really nailed it, too, it went all the way in. And when I pulled it out, you wouldn't believe how bad it was bleeding! My roommate, who laughed when he saw me do it, started freaking out. It seriously looked like I'd sliced a toe off, I must've hit a vein or something. But, anyway, yeah, that hurt pretty bad, but it made my roommate feel bad for laughing, so that was good.
