Here’s the game: come up with a plausible explanation for everyday facts and phenomena.  The key is plausible, something you could tell a group of people and they would actually believe it.  These are joke answers, obviously, but make the jokes believable if you can.  Winners of best answer will be declared the winner can pick next time’s fact.  Our winner from last time: Zeussical, who selected this week’s topic.
