A meeting is ongoing about how to best resolve conflicts that have
   arisen between the people who drive the elephants, and the people who
   drive the derricks, and what this might mean for future lightbulb
   installation work.
   A man comes by with a ladder long enough to reach the ceiling.
   "Excuse me, I'm from the code inspector's office, it's time test your
   electrical wiring."
   "Oh, we're working off a backup power supply, go right ahead!"
   The man arranges the ladder, climbs up to the lightbulb socket, and
   makes use of some device he has.
