The Tonight Show has a handsome list of throwback guests, Will Ferrell and Tom Hanks who were the first and second guests when Conan O'Brien took over, on what is presumed to be his last show this Friday. Seriously, they still haven't resolved this thing. Say what you will about the dunderheads-in-chief at NBC, but at least they are consistent at failing.

And while it is nice to remind the audience and the network of the heavy hitters that Conan will have in his corner when he bids his former employer farewell, I'd like to see him take it one step further. Conan O'Brien should have Jay Leno (yes THAT Jay Leno, is there another?) as his final guest.

Sure, it sounds like a bigger pipe dream than mounting a Van Halen reunion tour with the undead corpse of Jimi Hendrix as the opening act, but here's five reasons why it would not only make sense for another small chapter of The Tonight Show dynasty, but for the television dynasty as a whole.
