Michael Jordan and Muhammad Ali have been restored to their respective primes in order to engage in the the latest Epic Rap Battle of History, and GMS is finding it hard to separate the respective global icons.
The Chicago Bulls legend and former heavyweight champ, with the roles assumed by comedians Keegan-Michael Key and Jordan Peele, are seen to trade a variety of barbs and burns as both bid to be crowned the winner.
Ali, a wonderful orator in his pomp, delivers his lines with trademark panache and gusto, but Jordan is not to be outdone, and is able to draw on his acting experience in Space Jam to give his performance extra gravitas.
Watch the video above to check out the battle, and comment below with who you believe is the worthy winner. It's really important.
Jordan v Ali is the latest in a long line of videos from Epic Rap Battles of History, with previous efforts including Black Beard v Al Capone, Frank Sinatra v Freddie Mercury and Batman v Sherlock Holmes.
There is also a video during which Santa takes on Moses, with the role of the latter taken by Snoop Dogg.
