So David Letterman is gonna retire. As a fellow Ball State grad, I almost hate to say it, but sooo don't care. Never got into him and his snide, sneering snottiness. Of all the replacement contenders, most of whom I've just seen snippets of here and there, I'd put my vote in for Craig Ferguson. His show is almost entirely improvised, which gives it an immediacy the more scripted shows don't have.
