One of Barbie's sharpest jabs comes late in the movie, once Ken has taken over Barbieland and turned it into his personal man cave. Deprogramming the other Barbies from their patriarchy-induced objectification means distracting the Kens, which President Barbie achieves by offering to watch The Godfather with one of them. "Oh my God, you've never seen The Godfather!" he gushes while the other Barbies lead his brainwashed paramour away for deprogramming.
