I was once stopped by an elderly couple.

One side of the couple was arguing that the sun went out at night.

The other couple was arguing that the moon covered over the sun at night, and that's why we couldn't see the sun.

They asked me to clarify which one of them was correct as an independent third party, and I told them that the earth rotates, and so when you can't see the sun, it's because it's on the other side of the planet.

They both paused for a moment, looked at each other, and then looked at me and said, "oh, yeah", and that was the end of the argument.
