A History of the World, I Guess: Bill Wurtz's CLEAN version

Here's an engaging history of the world (this is the clean, school version--yes, there's a not-so-clean version).

It was made by Bill Wurtz who also made a history of Japan that was released in 2015 and  earned over 3 million views on its first day. But be careful. Look for the clean version before showing it to your class.
