Sun.
Somewhere in Pennsylvania, Anne Merak works as an assistant to the sun. She's been in that line of work for as long she can recall. At the end of every night, Anne raises her arms and pushes the sun up into the sky. Lowering her arms at day's end she puts the sun down to bed on the horizon.
She was very small when she started this job, and she's never missed a shift.
Half a century ago, she was declared insane. Since then Anne has gone through several institutions, been treated by numerous psychiatrits, and swallowed innumerable pills.
They never managed to cure her.
Thank heavens.
