Now that Neil Patrick Harris has as good as retracted his remark about How I Met Your Mother not needing stunt casting to improve its ratings, the sitcom has been made safe for the return of Britney Spears, whose guest appearance not long ago was wildly overpraised simply because she wasn't awful. She'll probably be Emmy-nominated. Since she's reprising her role as the receptionist in a dermatologist's office, we can only hope Sarah Chalke will return as the dermatologist. Meanwhile, series regular Jason Segel almost seems like stunt casting these days. (Peeps; photo via Socialite's Life)
