As we mentioned Monday, for some reason Michael Cera spent some time with the cast of Jersey Shore. He sandwiched Snooki whilst getting a lesson in fist-pumping, Pauly D gave him his famous crown hair-do, and as seen in the video below... Cera joins the guidettes ladies and guidos gentlemen in a hot tub above Manhattan, where he discusses taking his new style on Letterman that night (alas, it doesn't look like he did).

This Jersey Shore thing is getting bigger than Snooki's poof, so it's safe to say the protesters lost this battle. And it's being reported that the original cast is slated for another season in Seaside Heights.
