Yeah that is too bad about losing the voice of Chef Chef, though I have to admit I forgot it was Isaac Hayes, but how hard can it be to find another deep booming voice to do the character if they want to continue him.
I go through spells of watching it and then not. It usually comes to my aid when I'm taking things in the world way to seriously, then I start watching it and the Daily Show again. I've never seen the episode the Scientologist crowd is up in arms about, hopefully it will make it to the DVD release.
