It's safe to say that Diane Keaton doesn't understand the mechanics of beer pong, or perhaps she does and just decided to troll 'Tonight Show' host Jimmy Fallon -- hard -- with a spin on one of his very favorite games. After all, Keaton already spent her visit to the show to lecture Fallon on how to make his self-professed "beady" eyes look more alive, so she's clearly not opposed to some good-natured ribbing.

Or maybe she just likes red wine. With ice. No matter what her motivation may have been, Keaton flipped the script on Fallon's beer pong game in nearly every way imaginable. She drank wine. She thought it was a reward to drink. She yelled a lot. Beer pong -- wine pong? -- will never be the same.
