Zack Sharf Digital News Director SPOILER ALERT: This story contains spoilers for “Barbie,” now playing in theaters nationwide. Greta Gerwig’s “Barbie” ends with an ingenious final joke. Margot Robbie’s eponymous doll has become human and appears to be walking into a job interview when it’s revealed that she’s actually at a doctor’s office. “I’m here to see my gynecologist,” Barbie says with a huge smile despite not having any genitals (which is joked about earlier in the film). The movie cuts to black. “With this film, it was important for me that everything operated on at least two levels,” Gerwig told USA Today about crafting that final line. “I knew I wanted to end on a mic drop kind of joke, but I also find it very emotional. When I was a teenage girl, I remember growing up and being embarrassed about my body, and just feeling ashamed in a way that I couldn’t even describe. It felt like everything had to be hidden.
