They hold a runoff election.
Twenty. 1 to hold the bulb 2 to turn the ladder and 17 to be on the guest list.
Ticket closed: Forwarded to facilities.
Two. One to hold the bulb, and one to drink until the room starts spinning.
It's independent of population size.
Three - one to change it, one to not-change it and one to both change-and not-change it.
They tell you.
Just one. He holds up the light bulb, and the world revolves around him
Only one. She stands with the bulb and the world revolves around her.
Just one. They hold it in place while the world revolves around them.
