Also, Margaret Cho feels “sad†for Anthony Weiner because she accidentally sexted her own mom once; a much trimmer and taller Riley Griffiths tells Conan O’Brien how he gave director J.J. Abrams a near heart attack in a prank involving the super-secret script for Super 8; and Jimmy Fallon shows Jada Pinkett Smith the touching thank-you card sent by daughter Willow Smith. Watch our compilation to see what you missed.
