The world would be a lot better place if all the countries can just hold rap battles instead of bombing each other. But unless epic rap battles can somehow line the pockets of war contractors that’s not going to happen anytime soon. Thankfully, we can turn to each other (specifically clever YouTubers) to fill our craving for an old skool beef settled by mad lyrics.

Epic Rap Battles of History have pitted notable movie characters, actors and scholars to a lyrical showdown that’s a combination of the movie 8 Mile, an SNL skit and a history lesson.

Here’s five epic rap battles of history we wished really happened.

BRUCE LEE VS CLINT EASTWOOD

STEVE JOBS VS BILL GATES

ALBERT EINSTEIN VS STEPHEN HAWKING

MASTER CHIEF VS LEONIDAS

CLEOPATRA VS MARILYN MONROE
