Epic Rap Battles of History is back for season four, and they’re kicking things off on the right note. Their brand new video features the “Ghostbusters vs. Mythbusters,” and the rap is hilarious. Also, the guys playing Jamie Hyneman and Adam Savage (Nice Peter and EpicLLOYD, respectively) look enough like the characters to make it even funnier. Plus, there’s bonus Stay Puft!
Watch the musical fight after the break.
