Coffee Shop: Who is the best late night host?

It just goes to show you that in this economy, nobody is truly safe from getting screwed over by "the man." In the case of current Tonight Show host Conan O’Brien, "the man" is NBC–who promoted him to the show less than a year ago, only to decide they wanna bump former host Jay Leno back into the prized 11:35 p.m. time slot. Now Conan is on his way to greener, less unscrupulous pastures. All of the politics aside, we wanna know: Who is the best late night talk show host? Actually, why don’t you rank them for us and let us know what you like (and don’t like). Cool?
