Free historical hint: The first Roman Emperor to use the name 'Caesar' without being given it at birth was the usurper Servius Galba, who claimed the title "Imperator Caesar" in AD 68. So while the man I'm thinking about has 'Caesar' in his name, it was a family name and not a title.
You may be thinking about the rumor that Julius Caesar made the hoop earring famous, but at this time in history, most men and women commonly wore earrings as a status symbol. It's possible that all emperors had their ears pierced.
Update on the Louvre Robbery: there are four more being arrested today, unfortunately there's no trace of the jewels being found since October 19th according to BBC News.
You know, there was a question from one of my fb pages I follow that asked, if time travel were possible what event would you visit in history and change. My response was that I'd stop or make sure Hitler were never born. And then I began thinking about it. And thought....how would that change ACME? Would we still be Anerican and international? Would we still have The united nations and NATO?
