Sherrie Silver, the choreographer responsible for Childish Gambino's hyperviral "This is America" video earlier this year, shows off her own dance skills in a video by the U.K.'s National AIDS Trust highlighting World AIDS Day on Dec. 1. 

The ad, by London agency St. Luke's, shows Silver pulling some incredible moves to "A Little Respect" by Erasure in an empty dance studio with a red ribbon -- watched at one point by a deadpan security guard with a cup of tea as she glides across the floor in an office chair. The final voiceover, with the tagline "Rock the Ribbon," is by actor Stephen Fry. 

Directed by James Fitzgerald through Sonny, the film will be screened prior to all movies at London’s Regent Street Cinema throughout December and is part of a national multimedia campaign that also includes a dance-themed event at the Westfield London mall, which will encourage the public to rock the ribbon themselves through a dance mat and giant OOH screen.
