President Obama announced last week that he would award Ellen DeGeneres and 20 other high-profile people the Presidential Medal of Freedom for making significant contributions to the country.
On Tuesday, Ellen and her fellow medal winners descended on the White House for the ceremony. She had a little trouble getting in, though, because she apparently forgot her ID.
But when Ellen finally did get in, she didn't disappoint. She made all the other medal recipients pose for probably the most epic, star-studded mannequin challenge of all time.
It's all kinda blurry, but there's Robert De Niro kicking things off.
