In a video filmed by singer John Legend, US President Barack Obama appears with his wife Michelle performing part of the "Single Ladies" routine. He also briefly performed the hand-twirl move from the song's video at the Obama Inaugural Celebration. This video prompted an Obama look-alike, Iman Crosson, to do his own version of the "Single Ladies" choreography. Several other well-known personalities, including American environmentalist and politician Joe Nation and American actor Tom Hanks, have performed the dance. In the music video for "Dancin on Me" by DJ Webstar and Jim Jones, three females are featured in the background, imitating the "Single Ladies" dance. Jenna Ushkowitz, Chris Colfer and Heather Morris did the "Single Ladies" dance as part of the Glee Live tour in June 2011. The music minister at Geyer Springs First Baptist Church in Little Rock, Arkansas, thought it would be "an excellent idea" to attract interest in the church choir by using a remix of "Single Ladies" and having choir members dance to it. In the music video he made, the choir members sing, "All the singing ladies, all the singing fellas ... If you like the choir, then won't you come and sing in it." Cyndi Wilkerson, Music Ministry Assistant at Geyer Springs First Baptist Church, uploaded the video to YouTube on August 29, 2011. In April 2013, YouTube phenomenon Psy did the dance routine during a concert in Seoul while wearing a red leotard and red boots. A television advert for the South African cellular service Vodacom, used the song as a backdrop to an actor who was humorously mimicking Beyoncé's dancing, the advert quickly went viral and spawed several different variations.
