MC Hammer, Psy ‘Gangnam’ at AMAs

Stop. Gangnam time. MC Hammer joined South Korean pop sensation Psy on stage at the American Music Awards on Sunday to perform his hit song “Gangnam Style.” Everyone from Chinese activist Ai Weiwei to Madonna has gotten in on the song and its goofy horse dance, and the ’90s star was the latest to ham it up. Psy wore the harem pants MC Hammer made iconic in his music video for the song “U Can’t Touch This.”
