From Raxacoricofallapatorius with Love (TV story)

Overview
Funny for Money is the title of a special mini-episode of The Sarah Jane Adventures, scheduled for broadcast on 13 March 2009 as part of the 2009 Comic Relief appeal. It marks the first time one of the Doctor Who spinoffs has been featured in a mini-episode and is the first "mainstream Whoniverse" Comic Relief mini-episode (the previous production, The Curse of Fatal Death, was a spoof and not considered part of mainstream continuity, although it remains to be seen if Funny for Money will indeed be canonical, like the Children in Need Doctor Who mini-episodes. It also has yet to be announced whether Funny for Money will later see DVD release like other recent mini-episodes.

Special guest Ronnie Corbett will join K-9 to stop the return of an old enemy.


 * However, sarahjane.tv said it would feature "an attack by the rednosicles".

The title and story information were released on the BBC website.
