From Raxacoricofallapatorius with Love (TV story)

This episode was a special episode of The Sarah Jane Adventures that was broadcast on 13 March 2009 as part of the 2009 Comic Relief appeal.

Synopsis
While performing a maintenance on Mr Smith, a surprising guest visits Sarah Jane.

Plot
Sarah Jane, Luke, Rani and Clyde are running a routine check on Mr Smith, concluding with manual calibration of the energy reversal beam. Before they get the chance to calibrate it however, the entire attic starts shaking and Mr Smith warns them of an unknown force locking in on their location. Just as suddenly as it began, the shaking stops and a small man in a bowler hat teleports into the room.

The man greets them and tells them he is Ambassador Eranius, sent by the Galactic Alliance to thank them for protecting Earth. With a click of his fingers, he bestows upon them a gift: a set of sparkly red deeley boppers each. Confused, Clyde asks what they are for and Eranius cites cultural differences making humans very difficult to buy for. Eranius begins to make himself comfortable by hanging his hat on the back of the door and taking a seat. Whilst telling a story he proceeds to break wind noisily. This raises Sarah Jane's suspicions as they have encountered an alien race with "gas problems" before: the Slitheen Family.

Suddenly, K-9 teleports into the attic and identifies Eranius as a Slitheen. His cover blown, Eranius activates a device on his ring that attaches a clamp to K-9 which deactivates him. He then proceeds to unzip his forehead and peels off his skin to reveal his true form, before activating another device that roots Sarah Jane, Luke, Rani and Clyde to the floor through their "Deadly Deeley Boppers".

His enemies now immobilized, Eranius reveals that he plans to steal K-9. With it's extensive knowledge of the past and the future, no bank in space will be safe from them - they'll crunch the credit of the cosmos. With Eranius distracted by K-9, Luke reminds Sarah Jane of the energy reversal beam, but Sarah Jane reminds Luke in return that it is still un-calibrated and none of them can reach the switch. Clyde tells them to leave it to him as he grabs Eranius' hat off the door.

Sarah Jane gets Eranius' attention back, telling him she still has her Sonic lipstick. She signals to Clyde who throws the hat which hits the calibration switch. Mr Smith channels the energy reversal beam through the sonic lipstick meaning Eranius is now stuck to the floor and everyone else can move again. Sarah Jane tells Mr Smith to send Eranius back where he came from, along with K-9's clamp.

Sarah Jane claims that it was the weirdest five minutes of her life. K-9 agrees, a red nose adorning his face.

Story Notes

 * This episode 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).
 * Running at just over 5 minutes, it is the shortest mini-episode produced to date and, thus, the shortest episode to date ever produced for the Doctor Who franchise.
 * The title of the mini-episode comes from pre-broadcast publicity and does not actually appear on screen, making this only the second Doctor Who franchise episode in history to not display a title (the first being the 2005 Doctor Who Children in Need Special mini-episode).

Ratings
The episode was watched by approximately 8.3 million viewers according to unofficial over-night ratings.

Myths

 * The fansite sarahjane.tv claimed before transmission that this episode would feature an attack from an alien species called the Rednosicles.
 * Many fans speculated that this production would feature the Graske as the two Doctor Who mini-episodes DW: Attack of the Graske and Music of the Spheres and the two The Sarah Jane Adventures episodes SJA: Whatever Happened to Sarah Jane? and The Temptation of Sarah Jane Smith did before it. This proved incorrect, although Jimmy Vee, the actor who played the Graske on those previous occasions, does appear, but playing a Slitheen, instead.

Filming Locations

 * Upper Boat Studios

Discontinuity, Plot Holes, Errors

 * "Slitheen" are referred to as a race whereas they are actually a family within the Raxacoricofallapatorian race.
 * Eranius plans to steal K-9 Mark IV for it's extensive knowledge of the past and future. This model has only been activated since early 2007 so will not have experienced all that much. It is possible that this model has retained its memories of K-9 Mark III and possibly even those of Marks II and I before it when the Doctor created it.It is also possible that K9 has interfaced with Mr. Smith at some point.''
 * Just before donning the red nose, K-9 is heard laughing. Is the tin dog capabale of displaying such emotion? Although never before heard laughing, K-9 has been heard sounding indignant, smug, angry, and in othe emotional states in stories dating back to his debut in The Invisible Enemy. Sarah or one of the kids might have also adjusted his programming.
 * How did K-9 get his red nose?

Continuity

 * Presuming Ambassador Eranius was a real person, this is the first time in the series that a Raxacoricofallapatorian is seen wearing the skin suit of a non-human.
 * There are a handful of references to The Two Ronnies - a long-running TV series that Ronnie Corbett co-hosted - including Eranius saying that his nickname, "Rani", and Rani herself makes them "The Two Ranis", that whilst he was in the Galactic Canteen there were fork 'andles and when Eranius is finally teleported away, Sarah Jane says "And it's good night from him," which was Ronnie Barker's catchphrase.
 * With the exception of K-9, for no apparent (in-universe) reason donning a Comic Relief red nose, there is nothing in this mini-episode to suggest it cannot occur in mainstream continuity unlike the franchise's previous Comic Relief production, The Curse of Fatal Death, or the fourth wall-breaking Who mini-episode Music of the Spheres.

Timeline

 * Comic Relief Special occurs after: SJA: The Day of the Clown

DVD, Video and Other releases

 * It has yet to be announced whether the Comic Relief Special will later see DVD release like other recent mini-episodes.
 * The entire Comic Relief appeal appeared, segmented, on iPlayer within a few hours of broadcast.
