From the LA Times
CBS has ordered five more episodes of the Jenna Elfman sitcom "Accidentally on Purpose," a network rep confirmed.
The move is close to but not quite a vote of confidence in the series -- five episodes is fewer than the "back 9" that make up a full-season pickup. The news comes on the heels of a nice ratings bump for "Accidentally," which according to preliminary overnight numbers drew its best ratings Monday since the premiere.
