Jay Leno's last guest will be his successor, Conan O'Brien | Show Tracker | Los Angeles Times I've always liked Jay Leno so I'll try to catch this. I'll admit I don't watch the show regularly though. Out of all the evening comedy talk shows I prefer David Letterman. Anyway, do you plan to watch Jay's farewell show on the 29th? Do you think the Tonight Show will be better or worse with Conan O'Brien behind the desk?
