WATCH: What happens when you mix Benedict Cumberbatch with Kim Kardashian’s Booty?

Three-Word Stories of course!

Benedict Cumberbatch stopped by Jimmy Fallon’s Tonight Show last night where he got to play a brand-new game called "Three Word Stories."

The game goes like this:

In each round, one player has a word they have to get the other to say. To do this they have to create a story by only speaking to each other three words at a time.

We are in! This game will definitely be making an appearance around the dinner table this Christmas.
