Jimmy Fallon Plays Red-Wine-With-Ice-Pong With Diane Keaton
This is the Tonight Show in 2014, in which we learn that Annie Hall either doesn't know or just doesn't care how beer pong works.
In the Diane Keaton version of the game, you play with iced red wine, throw the ball directly at your opponent, and drink basically whenever you want. Drinking is also known as "winning."
Note to World Series of Beer Pong organizers: You may want to consider adopting Ms. Keaton's amendments to the official rules, because they are awesome.
