Watch the Vlogbrothers argue about Batman in song

A few months ago YouTube personalities John and Hank Green of the Vlogbrothers got into a debate about Batman (which you can watch here and here).

Since the YouTube community is a small one, The Gregory Brothers (of Auto-Tune the News and that catchy Unbreakable Kimmy Schmidt theme song) decided to turn the whole thing into a song. Good luck getting it out of your head.
