Dakota Johnson has the most epic (fake) breakup on 'Fallon'

Would you like to play a game? 

Oh, don't worry. Dakota Johnson isn't that extreme, but the 26-year-old actress did get a little buck on The Tonight Show last night while introducing Fallon to a new game.

“It’s called ‘the acting game,'" Johnson said during her brief primer. "I only played it once, just so you know, and it was over the holidays with my family and some friends. Basically, you get a fake scenario and you have to answer the phone and act out the scenario.”

The first scenario? Per Fallon's cue card: "It’s your fiancé, Darth Vader, calling to tell you he’s leaving you for another woman."

“Hi babe,” Johnson said after answering the fake call. “Did you just wake up?”

A pause... and then... 

"Who the (bleep)?” she hollered in fake indignation, proving that, if she doesn't know How to Be Single, she at least knows how to keep it real. Watch the full game below:
