What would have happened if, after Johnny Carson retired, The Tonight Show went to Jay Leno instead of David Letterman? I don't know how this would happen, maybe Johnny doesn't say anything on the topic or Letterman isn't as forceful, but I just want to know what happens if Letterman, probably my favorite talk show host ever, doesn't get his dream job. What happens to Leno's Tonight Show? Where does Dave go? And what happens to Conan O'Brien and Arsenio Hall in all this?
