Thursday’s debut of Comedy Central’s new series The Jeff Dunham Show pulled in 5.3 million viewers, setting a record for a series premiere on the network. Dunham, a ventriloquist-comedian who has headlined three stand-up specials for Comedy Central, drew generally negative reviews for his variety show, which features such politically incorrect puppets as Achmed the Dead Terrorist and the redneck Bubba J. Nevertheless, the half-hour premiere led the network to its highest-rated night of the year.
