Princess Celestia Gets Mugged is a My Little Pony: Friendship Is Magic fanfic written by BronyWriter.After having to deal with one annoying noble too many, Princess Celestia desperately needs a break. Thankfully, Luna, feeling sorry for her sister's plight, offers to take over for the day so Celestia can have a personal day. Disguising herself as a pegasus named Sunny Skies, Celestia goes off into Canterlot to enjoy herself.As fate would have it, she finds herself being mugged by a group of Stupid Crooks. Seeing the opportunity to finally have a bit of excitement, Celestia plays along by allowing herself to be kidnapped. As Celestia is enjoying the antics of her captors, Princess Luna mounts an attempt to rescue her sister.
Anger Born of Worry: Luna is quite furious at Celestia for the whole incident, but it's clear Luna had been genuinely worried and freaking out because she couldn't shake the spectre of something far more serious and sinister swallowing her sister.
Code Name: The Stupid Crooks decide to use these (Mr. Nacarat, Mr. Xanadu, Ms. Razzmatazz, and Ms. Fallow) so as not to get caught when they let their captive loose after getting the ransom. 'Sunny Skies' quickly points out she seen them in full view without them taking any pains to disguise themselves, which kind of defeats the purpose. This doesn't stop them from using the code names, but they realize this wasn't a good idea.
Dramatic Irony: The audience and Celestia know that she is in no danger whatsoever, as well as the fact 'Sunny Skies' is actually her. The other characters have no idea this is the case and that's were a lot of comedy comes from.
Earn Your Happy Ending: The kidnappers are pardoned by Celestia and Luna, are given jobs in the castle, and Luna now gets massages from Mr. Nacarat.
Epic Fail: A lot of the Stupid Crooks attempts. One not related to their 'kidnapping' is proceeding to let 'Sunny Skies' convince them to play poker with them. They end up losing all the money they stole from her.
Even Evil Has Standards: The crooks may be muggers and kidnappers, but they don't actually want to hurt 'Sunny Skies'.
They're also furious when they discover somepony kidnapped Celestia...until they figure out it's them.
Face Hoof: Celestia is sorely tempted to do this after a particularly stupid slip by her 'captors', only not doing so because she's tied up.
Go Karting with Bowser: In one chapter Celestia plays go fish and poker with her kidnappers and wins all the money they took from her.
Hell Hotel: Luna's punishment to the annoying nobility when revoking their moon pie privileges doesn't work is to make them stay at Hotel Moon, a rundown hotel 80 blocks from the palace. Their reaction is akin to it being this, but given this is Equestria, it probably isn't.
It Amused Me: Celestia lets herself be kidnapped simply because it seems like it'll be exciting and she knows the crooks couldn't hurt her even if they were competent.
Lima Syndrome: The kidnappers become more apologetic to Sunny Skies as the ordeal drags on. Once they get over the shock of finding out her real identity, they're probably very thankful they did.
No Sell: The crooks hit 'Sunny Skies' in the back of the head to try and knock her out. Celestia barely feels it and has to actively remember they're trying to knock her out before pretending they succeeded.
Later while the royal guard arrive to arrest them, one of them smacks her in the back of the head with a board to try and keep her quiet. The board breaks and she still barely notices.
Oh Crap: The Stupid Crooks have this reaction to realizing their 'captive' is Princess Celestia in disguise.
Pity the Kidnapper: Upon learning how stupid her kidnappers are, Celestia isn't sure to be mad at them or feel bad for them.
She does take pity on them and when they are caught they are given jobs in the castle and are pardoned.
Redemption Promotion: The kidnappers are spectacularly dumb during their attempts at crime, but after being pardoned, they seem to be doing a good enough job helping with the relief efforts in Canterlot's poor areas (and pranking uppity nobles).
Shipper on Deck: Celestia toward Luna and Mr. Nacarat after he is pardoned and is given a job as Luna's masseur. Most likely just to troll Luna.
Too Dumb to Live: The Stupid Crooks. When they send in the ransom note, they do so by having Mr. Nacarat walk up to the castle gates and hoof deliver it to the guards. And earlier, after finding out 'Sunny Skies' has an excellent memory and thus it's too late to blindfold her to hide their identities...
Mr. Nacarat: We'll get the money from the Princesses, and then we'll go to Manehattan to hide out until this blows over. I have a friend who runs a tavern in the lower-east side who can hide us until then.
Narration: Were she not tied up, Celestia would have given the crooks the double facehoof to end all double facehooves. It was getting to the point where she wasn't sure if she should be laughing at them or feeling sorry for them.
Wacky Cravings: Celestia and Luna's mother had this while she was pregnant with them according to Luna.
Luna snorted. "She ate peanut butter and pickle sandwiches with Us, Tia."
What Happened to the Mouse?: There were originally six kidnappers, but, by the end of the story, there were only four. Word of God said the last two escaped. In actuality, he edited them out of the story completely as there were too many to keep track of.
