The announcer is actually Australian, and does his best to affect an American accent (of course there's a few places where his upbringing sneak through, like when he says 'HQ'). Of course, that sort of fakery just makes me hate him even more.
I would so do this anyway, I don't care if there's a chance I'd die. There's a 100% chance I'm going to die anyway, just by living, and most of those other ways don't involve being launched from a siege weapon.
The guys on Mythbusters should die first, then we can all find out whether or not it's a myth that the show would be better without them.
