Jeff Dunham drops 55% in Week 2

This big of a drop would even hurt a dummy.

Comedy Central's polarizing ventriloquist series "The Jeff Dunham Show" fell a dizzying 55% in Week 2.

Dunham went from cable's #1 show last week with a premiere that set Comedy Central records ... to #3 on Thursday night, drawing 2.3 million viewers and a 1.0 rating.

One suspects a fair number of Dunham enthusiasts are also sports fans, so you have to factor the World Series drew more than a few away.
