A lightbulb is about 10 feet from the ground, held by a large screw-like contraption.

Large poles extend from the light-bulb holder. Hundreds of burly men push on the poles, slowly turning. Elephants, mules, tractors, are affixed to these poles, pulling and pulling on the workings of slowly lifting the light bulb toward the ceiling.

A bit off, scientists and engineers are studying lightbulb installation. Dust build-up. Alignment factors. Material stresses. Datacenters crunch numbers, burning killowatts of electricity and turning the flow of a nearby river to steam for cooling. Printers constantly print reams of numbers and charts, and flunkies review them in depth, traveling to and fro between the scientists and the laborers to adjust details around the process of raising the lightbulb toward the ceiling.

Often everybody is asked to stop. "Ohmygod." "We did it again!" "Reverse 1 foot and 3.17 inches." "Everybody about face!" "Those are my toes!" "Get your derrick away from my giraffe!" "On 3 now!" "One ...!" "Two .."

And the light bulb shakes.

Under rare conditions, it is possible to change a lightbulb.
