I did something REALLY stupid this weekend... All I have to say is, it doesn't matter what kind of a hurry you're in, if you are using power tools, always, always, ALWAYS, secure the piece being cut, sawn, gouged, doweled, routed, etc., to a firm, solid surface, unless you want to lose 1/3 of a fingernail, bleed all over your garage, get a whole LOT of stitches (the doc lost count) and have to take showers with your left hand wrapped in a baggie so the dressings don't get wet. And I don't even wanna think about the tetanus shot...
On the plus side, percoset is a wonderful pain reliever. But I wouldn't recommend getting a prescription by doing something stupid with a power tool.
