If you need a good laugh, you can always count on Epic Rap Battles in History. Hit their YouTube channel, and two minutes later you’ll have something to chuckle about all day. You probably shouldn’t do that at work, though, unless your boss is super cool with bluer language.

My favorites are probably Eastern Philosophers vs Western Philosophers, John Wick vs John Rambo vs John McLane, Romeo & Juliet vs Bonnie & Clyde, Al Capone vs Blackbeard, and Alexander the Great vs Ivan the Terrible
