Sources are claiming tonight's final Late Night with David Letterman runs long. Some say 12 minutes. Some say 17. My TiVo automatically updated and is allowing for the show to run one hour and 12 minutes but it still has the following program, The Late Late Show with James Corden, starting at its usual time of 12:37 and running one hour.
So if you want to catch Dave, I'd suggest padding his running time to an hour and twenty minutes, just in case. And if you want to catch Corden — well, I have no idea what time his show starts.
