Leno’s first week back as host of The Tonight Show continued Wednesday, with the late-night comedian welcoming the cast of Jersey Shore to the stage for a Celebrity All-Stars edition of “Jaywalking.” Here’s a given: no one on TV’s most controversial reality hit is a Rhodes Scholar. Six cast members from the popular docusoap appeared on Wednesday night’s special edition of Jay Leno’s classic bit, where the self-described “guidos” and “guidettes” participated in a trivia game during which they were asked “things you should have learned in school.”

-Sarah Palin would be in a line for the presidency if both President Obama and Vice President Biden were rendered unable to govern…..

-Snooki thinks J.D. Salinger wrote The Catcher In The Closet…..

-Barbara Walters looks a helluva lot like Joan Rivers…..
