how many does it take

A giant incandescent lightbulb hangs in a dark gray space. The bulb is not lit. Below it is parked a yellow truck with a cherrypicker. The cherrypicker extends up towards the bulb, and a worker wearing an orange and fluorescent green coat stands in the basket, reaching towards the lightbulb. It's unclear how the worker is going to change the bulb, since comparatively the light bulb is the size of a small house. The truck has an orange flashing light on top, several red triangular warning decals, and a few red and white hazard stripes. The painting is signed "Chris Silverman".
