Watching an actor break character and laugh is a rare treat on Saturday Night Live, but it's been much more common in recent seasons with Kate McKinnon in the mix.

Her latest victim was guest host Margot Robbie, who couldn't hold back the giggles as McKinnon riffed on sexism in Hollywood as an old-timey actress who's seen some sh*t. It happened somewhere between the opiate injections and shovel smacks from Clark Gable.

The skit is framed as a discussion of sexism in Hollywood during an actress round table from the New York Film Festival, but you'll be hard-pressed to focus on anything else once Robbie loses it.
