Margot Robbie, co-star of the new film Whiskey Tango Foxtrot and portrayer of Harley Quinn in the upcoming DC Comics movie Suicide Squad, visited Jimmy Fallon last night to play "The Whisper Challenge."

The challenge: Guess random phrases spoken by your partner while wearing noise-canceling headphones. It's not easy! See how she and Jimmy do, and watch the rest of the best late-night TV you missed.
