Arsenio was a great host. His jokes were always topical and funny- and having a host that wasn't like your typical late nite guy was refreshing. The barking and fist pumping did get old after a while, but if they phased that out, and kept revamping the show- I really don't see why he couldn't have lasted a lot longer. He was a lot funnier than Jay Leno is now. And Dave Letterman leaves a lot to be desired sometimes, since he targets mostly older audiences. Now, the only late night show that younger people have is The Daily Show and Jimmy Kimmel ( I know Arsenio is funnier than that guy).
Now, I realize my classification should be "Bring it Back!"
