15. McKayla Maroney Is Not Impressed
United States Olympic gymnast McKayla Maroney was the favorite to win the gold medal for vaulting at the 2012 games, but a miscalculation on her second attempt meant that she would place second and take the silver. A photo was taken of Maroney on the medal podium with an unfavorable facial expression that was instantly turned into a meme, and the Tumblr "McKayla is Not Impressed" was created. Maroney also went on the Colbert Report and later met President Obama, who got his own "unimpressed" meme treatment.
