Remember when Joaquin Phoenix showed up on The Late Show with David Letterman, bushy and seemingly drugged out of his mind?
That was weird.
In a way, the following video is even weirder.
It depicts Miley Cyrus alongside the eccentric actor, as she shows him how to assist a cause dear to her heart: To Write Love on Her Arms, a non-profit organization that specializes in suicide prevention.
She also tells him about Lady GaGa and sings some lines from "Bad Romance." It's as random as it can get, but, hey, whatever sheds light on this important charity...
