Pirate!

Pirate ROCKS.

Pirate, who is 7, was staying that she wanted to stay up and see Santa.  I told her that she couldn't, because he was unobservable.  Then I jokingly suggested that it was a quantum effect.  Then, having started that, she wouldn't let it rest until I explained Heisenberg's uncertainty principle, wave-particle duality, the double slit experiment, quantum superposition, and quantum decoherence.

"Aha!", said Pirate.  "Now I know how Santa gets to every house in the world on one night.  He's in a superposition, and he visits all of them at once and puts presents under every tree at once!"

But of course. Otherwise he'd have to travel so fast that he'd be immediately vaporized due to atmospheric friction. And if he could withstand that, then he'd be moving so fast that the shockwave would probably destroy most buildings and even tear significant portions of the atmosphere away from the planet.
