Boss: Do you have a minute to answer an engineering question? My wife is out of town visiting her sister. She asked me to put up the holiday lights while she was gone. I hired a homeless guy to do it and he fell off the roof. What's the easiest way to get rid of the body before my wife comes home? Dilbert: Your question is disturbing, but I'm intrigued by the engineering part. Here's a design for a catapult you can build at home. And here's a satellite map showing the best flight path to a neighbor's pool. Did he die right away? Boss: No, just a broken leg.
