Dakota Fallon was a guest last week on The Tonight Show With Jimmy Fallon, and she managed to do something only a handful of the late night host’s guests cab claim.

It was while playing a game–one Dakota Fallon was teaching to Jimmy Fallon–that she inadvertently dropped the F-bomb. Fortunately the show is pre-recorded hours before it hits the air, so her expletive was bleeped out.

The Fifty Shades of Grey actress introduced Jimmy Fallon to what she called “The Acting Game.” She explained that her family played it over the holidays. (Dakota Johnson is the daughter of Melanie Griffith and Don Johnson.)

The object is to act out a given scenario when answering the phone. Dakota Johnson’s scenario was that her fiance, who just happened to be Darth Vader, was calling to say he was leaving her for another woman.

“Hi babe, did you just wake up?” Dakota Johnson asked. “You’re what? Where are you?! Who the f**k?”

Jimmy Fallon–while laughing hysterically–told her to hang up the phone.

Dakota Johnson proved earlier in January that she can take whatever comes her way in stride. While at the Peoples Choice Awards Leslie Mann accidentally broke the zipper on her crop top when the two embraced.

“Leslie just broke my dress,” Johnson said as she accepted her award for Favorite Dramatic Movie Actress. “OK, well it’s not like nobody hasn’t already seen my boobs.”

Wouldn’t you love to try your hand at her game? Of course it might not be as much fun if Jimmy Fallon isn’t on hand.
