Apologies, Your Honor

So I recently came across this great aggregation of somewhat absurd honorifics:

ask.metafilter.com/327625/What-blatantly-ridiculous-titles-can-I-give-myself

With this in mind, here are some equally ridiculous prompts:

1) Write a character who lives an ordinary life but insists on being called by an over-the-top honorific. At some point, it turns out the Viscomte Twice-Removed of Their Imperial Majesties' Army Emeritus is, in fact, the highest honor where they come from...

2) A character goes to a dinner party / charity gala / high school reunion and jokingly introduces themselves using some absurd honorific. The herald (or other person doing introductions) doesn't catch on, and the next guest is introduced as the Lady Gertrude Abernathy, Dame of the Twelfth Dominion. There's no going back now - your character doubles down on their act.

3) Character meets a contingent from another civilization and performs a minor favor for them; for the rest of the trip, the aliens/elves/other refer to the character only by their new nickname. They keep trying to insist that's not their name, but the aliens/elves/other take no notice so character resigns themselves to it. Years later, they find out their coming was foretold by great prophecy, and the nickname is the name of the prophecied hero of the nation. [Note: this one gets funnier the more mundane the name, and the smaller the task. The Fated Champion of Qvrkfolk who saves them from a dragon is a trope; the guy trying to get home from work who helps some oddly dressed tourists change a tire on their minivan and is errantly but adoringly referred to as Steve for the rest of the story finds out that the aliens from the minivan were in a bind but now that they're back in their intergalactic empire are eternally grateful... ]

4) Your protagonist collides with a stranger on the sidewalk.

"Who do you think you are?" the stranger snaps.

"The Royal Imperator of Quince," character snaps back. "Who are you?"

Unfortunately for them, the Royal Imperator of Quince is a very important role in the kingdom of Qvrk, one that has been empty for hundreds of years. An emissary of Qvrk overhears and brings character back to Qvrm before they have the chance to protest that they don't even know what the Royal Imperator is supposed to do. They had better figure it out quickly though - Qvrm is preparing to go to war with their neighbors to the south, and people are starting to make comments that they're glad the Imperator is there to lead the armies into battle and ensure victory.

5) Your character is invited to a dinner party at a magician's house. They show up dressed nicely - an everyone else is in costume.

"Who are you supposed to be?" one of the other guests demands.

Your character makes up an absurd title, and plays the role for the duration of the party. The host winks knowingly when your character introduces themselves, but lets the bending of the rules go unchallenged. The next morning, your character receives a piece of mail "humbly submitted to his lordship, the Grand Vizier Steve, Baronet of the Western Lands and Minister of the Wardrobe". As the week progresses, they find their life slowly being eclipsed by their fictional persona. [Extension: they try to return to the magician's house to ask him how to fix their conundrum, but the house is no longer there and never has been].
