Think about a new talk show that NBC or CBS wanted to produce that included all David Letterman, Jay Leno, Jimmy Kimmel, Conan O’Brien, Jimmy Fallon, and Ellen DeGeneres. It could be a nightmare, but hey, it could also be legendary. Not counting the various preferences in content and comedy, there are ways they each like to run their show, ways they prefer to tell their jokes, ways they interview guests, etc. That could cause disengagement, animosity, jealousy, and basically spark a fire from them being in the same room together. However, because of their diverse experiences, talents, skills, ideas, it could be the best talk show to ever air on the planet.
