LOL! See Psy Teach the Jersey Shore Cast to "Gangnam Style"

Pauly D, Snooki and Vinny's signature fist pump just got a serious upgrade -- with a little help from Korean superstar Psy.

"Gangnam fist pump style!" Pauly D yells triumphantly, as he "beats the beat up" to the smash single.

The MTV standouts aren't the first celebs to give Psy's moves a try; the 34-year-old artist's video, which currently boasts 591 million YouTube hits, has inspired stars like Britney Spears and Maria Menounos to get their "Gangnam Style" groove on too.

Most recently, Psy proved his song is much more than a catchy dance hit: the singer/songwriter showed off its peace-building potential on the ultimate international stage Oct. 23, teaching U.N. Secretary General Ban Ki-moon his oh-so-fly moves.
