These people like to live dangerously but don't tell their bosses that, or OSHA. 

Sometimes your ladder is too short to reach where you need it to. Sometimes you need a nap and the only place to sneak some shut-eye is on the woodchipper. Life can be dangerous enough as is, but when you combine construction workers cutting corners, you find yourself in new, even more dangerous places than you should. 

We hope for your sake that you aren't dangling from a shaky ladder or aren't standing on a giant geodesic sphere without a harness, but if you are, then you're going to feel right at home with your fellow danger seekers.
