Hank points out that seeing lots of weird things in the sky, becomes pretty common after there's a single sighting of something, because people start looking up at the sky and aren't familiar with what they're looking at. 

Hank and John Green always bring about such measured, thoughtful, and nuanced responses to the events going on around us. Thankful for the treasure trove of fun, insightful, and very educational videos Crash Course has brought to us.
