My first summer job was doing IT for a small outfit, who worked out of an old house converted into an office. They had eight machines, all connected to a LaserJet printer via a parallel port switch. The parallel cables ran down into a crawlspace under the house, and it wasn't uncommon for one of the cables to work its way loose. No problem, tighten the parallel port connection at both ends, and you're back in business. But, being an old house, many outlets were missing ground pins. I must of electrocuted myself twenty times that summer.
