It has been five years since the BP oil spill, and Jimmy Fallon says tar balls are still a problem in the ocean. So in honor of Earth Day, the "Tonight Show" host and Russell Crowe broke out Fallon's old protest song.

Maybe this time big oil will finally get the message. If not, it's good knowing Fallon and celebs are here to remind us not to go swimming down in the south. Well, that is unless you want (tar) "balls in your mouth."

"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
