"The Jeff Dunham Show" 9 p.m. Comedy Central: It has been a long time since a comic-ventriloquist has had his own TV show. It was worth waiting for someone as good as Jeff Dunham to come along. He's already a hit with more than four million DVD sales and 360 million views on YouTube. Now Dunham and his merry band of characters can add hit TV series to the list. It is not just the odd group of characters like Walter, Achmed the Dead Terrorist, Peanut, Bubba J or Jose Jalapeno on a Stick that make him funny. It is Dunham's dry and quick wit that makes his act and this cable series work. He's the funniest man with a cloth character on his hand since the Muppets heyday.
