Fox has ordered a fourth season of American Dad.
The network wants 22 episodes of Seth MacFarlane's B-show, scheduled for 2008-2009.
Dad has become an important part of Fox's Sunday night animated lineup, right up there with The Simpsons and MacFarlane's Family Guy controversial (controversial as in weak) Family Guy.
The order brings the total number of Dad episodes to 84, which now means the series can be sold into syndiction and run every day forever.
