To say farewell to what has been a great year, Psy took part in ABC’s “Dick Clark’s New Year’s Rockin’ Eve” at Times Square in New York.

For the performance, Psy trotted out several memorable characters from the song’s music video, including crotch-thrusting elevator guy, Noh Hong Chul and the yellow suit dancer, Yoo Jae Suk.

Psy also recruited the help of MC Hammer whom he already performed with at the American Music Awards in November. As it happened to also be Psy’s birthday that day, the host Ryan Seacrest led the crowd into wishing Psy a happy birthday.
