No, not “On The Floor” as in J. Lo, who turned it out quite admirably on American Idol last night with a live performance of the hit single from her released Love? album, but rather “Jersey Floor,” a skit from Late Night with Jimmy Fallon featuring Fallon’s former Saturday Night Live pals Rachel Dratch, Amy Poehler, and Tina Fey (and a solid Shake Weight visual joke), reunited in the name of riffing on the cultural herpes that is the Jersey Shore.

With Amy Poehler and Tina Fey both in the 30 Rock building, all signs point to Poehler making at least one appearance on SNL tomorrow. Fey is hosting with royals-approved musical guest, Ellie Goulding.
