Oscar-winning actress Diane Keaton stopped by “The Tonight Show Starring Jimmy Fallon” and in addition to promoting her new book, Fallon recruits her to play some good old-fashioned beer pong — except Keaton is using red wine. Oh dear.

Watch in the video above, it’s ridiculous and hilarious. Keaton, who apparently did not play a lot of beer pong at Orange Coast College, just catches Fallon’s ball, chugs her wine and declares, “I win! I win the game! I caught it in my hand!” Ha!

Below, Keaton sort of talks about her book, but mostly the interview consists of her making fun of Fallon and him cracking up about it. We could think of worse ways to spend five minutes than to have Diane Keaton crack jokes at our expense.

Her new book, “Let’s Just Say It Wasn’t Pretty,” is available now.
