Joaquin Phoenix is quirky. He's an artist. What did you expect?

Accepting his award for Best Performance by an Actor in a Motion Picture - Drama for "Joker," the actor jumped into climate change, and praising the awards show for the "bold move of making tonight plant based," referencing the meat free menu at tonight's event.

Phoenix also thanked his fellow nominees, saying, "I really do feel honored to be honored with you."

He thanked "Joker" director Todd Phillips, calling him an "amazing friend and collaborator."

Phoenix added that he was "such a pain in the ass" he can't believe people on the film put up with him.

He thanked his fianceé Rooney Mara, and sent well wishes to Australia.

"Together hopefully we can be unified and hopefully make some changes," he said.
