We're learning more about this terrible tragedy.
Bros be warned! Diane Keaton breaks basically every rule of beer pong in this video! We know how you might find that devastatingly upsetting.
Well, she didn't necessarily play beer pong so much as red-wine-with-ice pong!
That's right, on The Tonight Show Jimmy Fallon and Diane literally go balls to the wall in a bout for the ages!
Not to spoil anything, but Jimmy ends up putting his balls all over Diane, and Diane, well, she does the same!
Watch the clip that descends into madness and chaos (above)!!!
