Nanageddon coming with a demon in a wig
In "Nanageddon", Vince Noir (sorry, Obsidian Blackbird McNight) has gone goth, and Howard follows him once he hears that Vince is having two sexy goth girls over. In order to impress the girls, Vince borrows Naboo's spellbook, and summons a demon — who looks like a little old lady. Unfortunately, this demon, Nanatoo, is the most dangerous arch-demon of them all, and she has absconded with the spellbook, threatening to raise an army of evil Nanas and bring on Armaggedon.
The Shaman Council assembles. They revoke Naboo's shaman powers as punishment for allowing Nanatoo to get loose, and assign a crack team of shamans, Saboo and Tony Harrison, to track down and defeat Nanatoo. Meanwhile, Vince and Howard go undercover to try to steal the tome from Nanatoo to return to Naboo.
Vince and Howard successfully steal the spellbook, but Nanatoo corners them in their apartment. Fortunately they are able to defeat her.
The Mighty Boosh episode "Nanageddon" contains these tropes:
- All for Nothing: Vince and Howard go through a lot of effort to impress the goth girls: completely changing their look, summoning a demon, almost causing the apocalypse, almost getting killed averting the apocalypse, but at the end of the episdoe the girls want nothing to do with them and would prefer to date Naboo and Bollo, an asexual alien and a gorilla, respectively.
- Asshole Victim: The first person Nanatoo kills is rude to her and disrespectful to the elderly generally before being brutally murdered.
- Attractive Bent-Gender: Howard comments that Vince is looking a little too pretty in his Nana disguise, and the bingo announcer finds him attractive in drag as well.
- Bathos: Howard ruins all of his attempts to sound dark with a nonsequitur. He gets all dark when talking about going to cemeteries or killing swans, but then ruins it all by claiming to have done a shit on whatever dark thing it was.
- Chekhov's Gun: Goth Juice, an extremely power hairspray introduced at the beginning of the episode as being able to freeze a satsuma in midair. At the end of the episode, Vince saves himself and Howard and buys Naboo time to un-summon Nanatoo using the hairspray to freeze her knitting needle in midair.
- Comedic Underwear Exposure: In his goth outfit, Howard wears impossibly tight jeans that he can barely walk in. When he gets up, he splits his trousers down the back, exposing his goofy-patterned briefs to the goth girls and triggering their derision.
- Cool and Unusual Punishment: Apparently the worst punishment doled out by a shaman is turning their back on you, which involves them slowly rotating backwards while a jaunty bass riff plays. Despite no obvious ill consequences to the recipient, the shamans treat it as a terrible terrible thing.
- "Darkness von Gothick" Name: Vince becomes Obsidian Blackbird McNight in his goth persona, and the two goth girls are Anthrax and Ebola. Oddly enough, Vince Noir and Howard Moon are already fairly dark and evocative names, so it's unclear why he felt the need to change his.
- Disguised in Drag: Howard and Vince go undercover as old ladies at the Bingo hall to track down Nanatoo. Howard refuses to shave his mustache for the disguise, while Vince gets a bit too into it and puts a lot of effort into his hair and makeup.
- Disney Villain Death: Saboo punts Tony Harrison off the flying carpet, causing him to fall forever, presumably to his death, though he's never shown hitting the ground.
- Evil Old Folks: Nanatoo is one of the foulest, strongest, evilest demons known, and she's threatening to raise an army of demonic old ladies just like her. She kills people in very old womanly ways, with knitting needles and a discount bus card.
- Games of the Elderly: Howard, Vince, and Saboo all immediately know to look for Nanatoo at a bingo hall. Unfortunately, there are so many old ladies there they don't know which one is her, though it turns out their hunch was correct.
- Immediate Self-Contradiction: When Vince asks Howard to clear out the apartment, Howard says he can't possibly because it's the one time a year he does anything, and his one friend depends on the company. Once Howard learns there will be girls involved, he immediately cancels using a vague, lame excuse.
- Improbable Weapon User: Nantoo uses knitting needles and knitting to kill her victims. She knits scarves at supernatural rates to restrain her victims, then lethally stabs them with the needles.
- Perky Goth: When cheerful, childish, manchild Vince becomes goth, he doesn't lose much of his old personality despite trying to act dark.
- Silver Vixen: Invoked by Vince in his old lady disguise. Howard comments that Vince is looking a little too nice in his outfit, while Vince insists that he's in disguise as an old lady who used to be a pin-up girl. The bingo announcer certainly finds him attractive.
- Summoning Ritual: Vince sets up a pentagram summoning circle with candles before doing his magic, which involves summoning. First he summons a bouquet of flowers using the "beige magic" book, then he summons Nanatoo.
- Throw the Dog a Bone: Howard, who's usually useless and a hindrance in everything he does, actually gets some surprising moments of competence. He comes up with the plan to track down Nanatoo, and then successfully steals the spellbook from her, while in the Bingo Hall it's Vince for once who ruins their plans. Howard is still terrible with the girls though.
- Tome of Eldritch Lore: The spellbook Vince uses to summon Nanatoo has a glowing pentagram on the cover and shakes slightly with magic. Naboo warns him against using it because it's too evil, and when Vince ignores his advice he summons the most dangerous demon of them all.
- Turn in Your Badge: Naboo loses his shaman powers for failing to properly uphold his duties. He pledges to atone for his actions and make things right, but Head Shaman Dennis (looking rather like Da Chief with his bald head and mustache) instead assigns the "case" to a duo that will do things by the book, and formally takes away Naboo's powers.
