Today is Willie Nelson's 80th birthday and turning 80 means you can officially stop giving a sh-t what people think of you and make videos auditioning for the role of Gandalf in The Hobbit 2 while making weed jokes with your son.

The video was the brainchild of Conan O'Brien, but Willie's the real star here, his long, wizard-like hair and shouts of, "You shall not unlit joint, man!" making him well-suited for the role.

Nelson earned the admiration of at least one person. Actor Ian McKellen, the real Gandalf, approved, tweeting, "Dear Willie, You are far too young to play Gandy. But nice try; have a stoner of a birthday. Love and admiration. Ian."
