Infamous quote from just before firing up the coil (which is on videotape
soundtrack of the incident:)  "I don't mind.  This place is a rental."

Also: if you're standing outside in the rain while crowds of fire trucks
gather on the street, the fire trucks' strobe lights will "freeze" the
raindrops, and you'll see a three dimensional array of sparks hanging in
the air.

Also: fire crews have really cool FLIR infrared cameras which can see
hotspots in your ceiling.
