thought of the day 2009 09 18 - danger!

I'm watching this thing about throwing weapons. Knives, axes, even things like screwdrivers, scissors and other improvised weapons. And of course at the beginning of it is the obligatory, "do not try this at home" warning. Which of course, I'm probably going to ignore, but even if I don't ignore it, i'm still a bit annoyed. How come every time someone says "it goes without saying" they go ahead and say it anyway? I mean, damn, if it goes without saying, then you shouldn't have to fucking say it right?
