This past May, Ellen Degeneres started the #JustKeepDancing challenge, inspired by her guest Braylon Beam, who used dancing to help cope during his battle with cancer. Fans have been uploading their videos to EllenTube, and celebrities have been challenging one another a la the Ice Bucket Challenge to promote the project and donate to St. Jude's Children's Research Hospital. 

Jon Stewart, in his retirement, has been having a good time winning Emmys and hosting wrestling events, and accepted the #JustKeepDancing challenge from new friend Triple H. With an assist from a cute little Stewart, Jon danced to O.G. Drake and challenged Stephanie McMahon to do the same.
