Epic Rap Battles of History is a popular YouTube series, but it seems like they might have released their epic-est battle yet, with a little help from Key & Peele's Keegan-Michael Key and Jordan Peele. Key plays Michael Jordan and Peele is Muhammad Ali. There are the references you expect and hope for — Space Jam, Vietnam, Hitler moustaches, etc. — and Ali calls Jordan a big dumb goblin. Perfection.
