Russell Crowe & Jimmy Fallon sing ‘Balls In Your Mouth’

As part of a celebration of Earth Day, Jimmy Fallon had actor and sometimes musician Russell Crowe on to perform a charming little ditty called “Balls In Your Mouth.” What does sucking on balls have to do with the environment? Well, these aren’t testicles- they’re the balls of tar created by the BP oil spill, which was a staggering five years ago. The track is about as sad and touching as a song called “Balls In Your Mouth” could be.
