CBS has ordered five more episodes of Jenna Elfman's CBS sitcom Accidentally on Purpose, which has improved upon retaining the ratings from its lead-in How I Met Your Mother. Depending on where your preferences are, Accidentally on Purpose ranges in quality between two of its cinematic predecessors, the oops-a-baby Knocked Up and the oops-a-baby-with-my-gay-friend-in-a-horrible-movie The Next Best Thing. Luckily, Elfman's series seems to be veering closer to the former. [THR]
