Why did the moonlight apply for the night shift?

It just wanted to shine when it mattered most.

Did You Know?

The joke works because moonlight literally shines at night — so applying for the night shift is when it can do what it does best! Moonlight isn't actually produced by the moon itself; it's reflected sunlight bouncing off the lunar surface. The moon reflects only about 12% of the sunlight that hits it, which is why moonlight appears so much dimmer than direct sunlight.
