Taking to the stage, the filmmaker said he wished he could 'split' the award in five to split it with his fellow nominees: Sam Mendes, Todd Phillips, Martin Scorsese and Quentin Tarantino. What a guy.
The 50-year-old, whose film won four awards on the night, said: "After winning Best International Feature, I thought I was done for the day and was ready to relax.
"Thank you so much. When I was young and studying cinema, there was a saying that I carved deep into my heart, which is that 'the most personal is the most creative'.
"That quote is from our great Martin Scorsese. When I was in school, I studied Martin Scorsese's films. Just to be nominated was a huge honour. I never thought I would win.
"When people in the US were not familiar with my films, Quentin always put my films on his list. He's here, thank you so much. Quentin, I love you.
"And Todd and Sam, great directors that I admire. If the Academy allows, I would like to get a Texas chainsaw, split the award into five and share it with all of you. Thank you. I will drink until next morning, thank you."
We reckon he's definitely earned those drinks, that's for sure.

As well as winning Best Director, Bong Joon-ho and Parasite also picked up awards for Best Foreign Language Film, Best Original Screenplay and finally Best Picture.
The last award of the night was one for the history books as it meant that Parasite became the first foreign language film to ever win Best Picture at the Academy Awards.
Taking to the stage with the rest of the team, producer Kwak Sin-ae said: "We never imagined this to ever happen. We are so happy. I feel like a very opportune moment in history is happening right now."

The psychological thriller - which was released in South Korea in May 2019 - stars Song Kang-ho, Lee Sun-kyun, Cho Yeo-jeong, Choi Woo-shik and Park So-dam.
It follows the Kim family, who are struggling to make ends meet while they live in a small basement apartment.
When one of them finds work with the much wealthier Park family as a tutor, the rest of the family decide to de-camp and infiltrate the Parks' home. Needless to say, that does not go too well for them.
