After a Reddit user posted a photo of his 72-year-old grandmother Geraldine Dodd at age 22, it went viral and caught the attention of her modern-day doppelganger Scarlett Johansson. The duo ultimately attended the Rough Night premiere together, and in the actress' words, got "kind of trashed!" 

"Oh my gosh, I have a doppelganger," ScarJo said on The Late Show in 2017. "This grandson posted it on Reddit and I don't have any social media presence. This came to me purely because people were like, 'Oh my God, you have a doppelganger and it's crazy. So I looked at this link online."
