-->"Dickens' classic tale of kindness, truth and virtue completely mucked up and ruined by having a member of the Blackadder family involved. Also Baldrick, of course, the man you can rely on to turn a Christmas dinner into a dog's dinner, as long as the dog isn't particularly fussy."

The special centers around yet another member of the Blackadder linage; in this case shopkeeper Ebenezer Blackadder, who lives in London during the Victorian times and is known as "kindest and loveliest man in all England", but unfortunately this reputation leads to many of his acquaintances and costumers constantly taking advantage of his kindness, leaving him in dire financial straits during Christmas.

Flat broke, he decides to just go to bed, since there's nothing left for him to stay up for. In the middle of the night, he is awoken by the Spirit of Christmas (Robbie Coltrane) who was asking for a drink, but decides to show Blackadder how horrible his ancestors were by means of visions (which, in terms of getting people to renounce their wrongful ways, are much more effective than line drawings).

Blackadder realises that there's profit in evil, and decides to take it out on everyone who he remotely dislikes.

!!Tropes:
* AndNowYouMustMarryMe: With a twist when Future!Blackadder tries this on Queen Asphyxia. Her response? [[spoiler: "I thought you'd never ask!"]]
* AnnoyingLaugh: Millicent has an extremely high-pitched and annoying laugh. (As we find out at the end, her crying is just as annoying).
* BeingGoodSucks: Everyone and their mother exploit Ebenezer for charity.
* {{Bowdlerization}}: Most versions of this special edit Baldrick's line about a dog being used as Jesus for the Nativity play to remove an additional line where Baldrick mentions the dog will be nailed to a cross for the Easter play. The earliest known case of this edit was on its first rerun in December 1989. The edited version has aired on UK terrestrial broadcasts on Christmas in the years 1998, 2007, 2008, 2010, 2012, and 2014.
* DeadpanSnarker: Unlike his ancestors, this Blackadder is generally a nice person, but still retains this trait but in a playful manner.
* EvilIsCool: Invoked by Blackadder, prompting his FaceHeelTurn.
* EvilOverlord: Queen Asphyxia in the future is a female example.
* ExtremeDoormat: Though the nicest member of the family tree, Ebenezer Blackadder is also a complete pushover and everyone takes advantage of his generosity, until the Spirit of Christmas arrives and inadvertently inspires him to be mean like his ancestors.
* EyepatchOfPower: Grand Admiral Blackadder.
* FanDisservice: Baldrick's attire in the far future.
-->'''Grand Admiral Blackadder''': For God's sake, Bladrick, if you're going to wear that ridiculous jock-strap, at least keep your legs together!
* FourStarBadass: One future Blackadder is the ruthless and brilliant Admiral of a thinly-disguised version of [[Franchise/StarWars the Empire]]. He seizes power.
* GeneralFailure: Grand Admiral Baldrick in the alternative future where Blackadder remains good. He's such an idiot he ends up bombing his own side.
* GoGoEnslavement: In the far-future segment, Blackadder and Baldrick wear nothing but a leather speedo and a leash when they're slaves.
* GratuitousGerman: Prince Albert.
* IllNeverTellYouWhatImTellingYou: Albert is absolutely terrible at keeping his surprises a secret.
* IHatePastMe: {{Averted}}; Ebenezer Blackadder is absolutely delighted to see the sort of underhanded behaviour in which his Elizabethan and Regency ancestors engaged to get ahead.
* LargeHam: Creator/RobbieColtrane as the Christmas Ghost.
* LaserGuidedKarma: Even if the story revels in inverting the usual message with the good and kind Blackadder deciding he'd be better off being selfish and nasty, he is also punished for it: at the start the royal family plan to shower him with wealth and land for being the kindest and most generous person in Britain, but he insults them and throws them out.
** Though given how easily everyone conned him back when he was nice, it's unlikely he would've kept the money for long.
* NiceJobBreakingItHero: The Ghost of Christmas Past, who sets out to congratulate Blackadder for being such a better man than his despicable ancestors, only to accidentally convince him that [[EvilIsCool being evil is way more fun]].
-->'''Spirit''': It points out a very clear lesson.
-->'''Ebenezer''': Namely?
-->'''Spirit''': Namely the rewards of virtue are largely spiritual, but all the better for it!
-->'''Ebenezer''': You don't think it points out the very clear lesson that bad guys have all the fun?!
* OhCrap:
-->'''Ebenezer''': Baldrick, it couldn't have been the Queen, because, when she visits people, she leaves them her Royal Seal.
-->'''Baldrick''': What, like this one?
-->'''Ebenezer''': Yes, just like [[OhCrap tha...]]
* PyrrhicVillainy: Blackadder's descendants will rule the universe, but Blackadder missed out on an opportunity to become incredibly rich.
* ShoutOut: One of Queen Asphyxia's court looks like Nursie's head grafted onto a knock-off [[Series/DoctorWho Dalek]].
** Grand Admiral Blackadders costume appears to have been inspired by Darth Vaderís suit.
* SmarterThanYouLook: Subverted with Baldrick. He can't read, write or count, but he's smart enough to question Ebenezer's StupidGood behavior and points out that the freeloaders (especially the obese orphans) don't need what he gives them. He's also smart enough to hide the turkey when they get visitors.
* SnarkToSnarkCombat: As always with Melchett, as seen in the Elizabethan section.
-->'''Blackadder''': I trust Christmas brings you its traditional mix of good food and violent stomach cramp.
-->'''Melchett''': And compliments of the season to you, Blackadder. May the Yuletide log slip from your fire and burn your house down.
* StartOfDarkness: Or a reboot of darkness, at least.
* StepfordSmiler: Ebenezer Blackadder seems to inwardly be just as perceptive and sardonic as his ancestors, but his myopic insistence on being good and charitable for virtue's sake means that he tends to grin and bear it whenever other people are clearly taking advantage of him.
* YetAnotherChristmasCarol: An inversion and parody. Indeed, when Ebenezer Blackadder, the [[WhiteSheep only good and friendly member of the Blackadder bloodline]] (and also an ExtremeDoormat), sees that his descendant would rule all of the universe if he became a spiteful miser like his ancestors (instead of being a slave to future Baldrick, which would happen if he were to remain kind and generous), he lampshades it gleefully:
-->'''Ebenezer:''' [[SpoofAesop Bad guys have all the fun]].
