Ya know, while at work today I took a break from the computer stuff to sketch out some concepts for plumbing that I'm going to rework at home for one of my hobbies, a pond.
Maybe I would be the guy in the OP that goes around fixing pipes! Then once I'm in the door I'd offer to install Linux on any computers I see.
