At the screenings for his stand-up concert film "Hilarious," Louis C.K. was more than generous with his time and sincerity in answering questions from fans in the audience afterward. He also opened up about his Twitter-hate for former Alaskan Governor Sarah Palin. C.K. has gone to Twitter in allegedly drunken states to bash Palin, and the last time he did so, he found himself a day later sitting next to her teen-aged daughter Bristol Palin on the set of "The Tonight Show" with Jay Leno, who coerced him into trying a dance move alongside Bristol Palin.
