This (Inappropriate" scene cut from script TV Series News (March 6, 2007)), made me laugh. A scene from the new series has been cut because Martha Jones (Freema Agyeman) was in just her underwear. Apparently it was unappropriate.
I reckon that is a thinly veiled reference to Primeval, which through a genius convoluted plot has ensured that Abby (Hannah from S-Club 7) is in her underwear every single time you see her at home! Last episode she even answered the door in knickers and a short t-shirt. For the ladies, that geek student was also in boxer shorts, a vest and socks. Not quite the same. I'm sure the other male characters would have been preferential.
(If you don't know, Abby is secretly looking after a pet dinosaur which looks like the thing from Surface. The dinosaur needs a very hot climate, therefore Hannah has to have her flat very hot, and therefore has to wear just underwear. Of course.)
Intellectual television at its finest.
