Henson and Lee battle to a place of grudging respect till spoiler Walt Disney shows up and (literally) owns them both.
Fun fact: Disney also owns Maker Studios, producer of Epic Rap Battles of History. Disclosure: I do work for Disney because it's almost impossible not to work for Disney.
The Epic Rap Battle team is touring this summer, including an upcoming stop at LA's Whiskey A Go Go on Sunday August 16.
