In an appearance on the 'Late Show' last night, David Letterman asked McKayla Maroney and her US Olympic Gymnastics teammates about the 16-year-old's now infamous "not impressed" look at the London Olympics.
McKayla admitted she made the face on the podium because she was disappointed with the silver medal, instead of the gold. But admitted she found it "really funny" how it's taken off as a meme.
McKayla and her teammates then went on to show their best "not impressed" looks.
Thanks to the look, fans have put the gymnast in everything from The Avengers to Sesame Street and Charlie Brown.
