Jimmy Fallon sure can fist pump!

The NBC comic and talk show host is back with a new installment of his hilarious spoof series "Jersey Floor," and only Us Weekly has your first look at the skit, which will air on Late Night With Jimmy Fallon September 20.

For this all-new episode -- which features Fallon and A-list pals being transformed into guidos and guidettes after a wild elevator ride to the "Jersey Floor" -- the comic had the chance to first pump with the actual Jersey Shore cast!

As these exclusive photos from the segment show, Fallon (aka J-Bro) isn't the only Saturday Night Live alum to party Jersey-style at 30 Rock. Rachel Dratch makes an appearance on Tuesday's episode, drinking and dancing with none other than Nicole "Snooki" Polizzi.

"They weren't afraid to poke fun at themselves and they helped teach some new dance moves. Merp!" Fallon, 36, tells Us exclusively of working with the cast.

The MTV cast's episode of Fallon's "Jersey Floor" episode airs on Late Night Tuesday at 12:35 a.m. (EST) on NBC. To watch previous episodes of "Jersey Floor," visit
