Thoughts lately -
1) If copper is so expensive now, why are pennies still only worth one cent?
2) What did medieval people think of static electricity?
3) There aren't many gender neutral insults, yet instead of being irritated by this I have found humor in it. For example, calling someone a douchebag is like saying, "You are a really useful hygienic tool." Calling someone a dickhead is like saying, "I don't need you. People have been cutting those off for centuries."
